END-INFO-DIR-ENTRY  File: gnutls.info, Node: OCSP API, Next: PKCS 12 API, Prev: PKCS 7 API, Up: API reference E.5 OCSP API ============ The following functions are for OCSP certificate status checking. Their prototypes lie in 'gnutls/ocsp.h'. gnutls_ocsp_req_add_cert ------------------------ -- Function: int gnutls_ocsp_req_add_cert (gnutls_ocsp_req_t REQ, gnutls_digest_algorithm_t DIGEST, gnutls_x509_crt_t ISSUER, gnutls_x509_crt_t CERT) REQ: should contain a 'gnutls_ocsp_req_t' type DIGEST: hash algorithm, a 'gnutls_digest_algorithm_t' value ISSUER: issuer of 'subject' certificate CERT: certificate to request status for This function will add another request to the OCSP request for a particular certificate. The issuer name hash, issuer key hash, and serial number fields is populated as follows. The issuer name and the serial number is taken from 'cert' . The issuer key is taken from 'issuer' . The hashed values will be hashed using the 'digest' algorithm, normally 'GNUTLS_DIG_SHA1' . *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error code is returned. gnutls_ocsp_req_add_cert_id --------------------------- -- Function: int gnutls_ocsp_req_add_cert_id (gnutls_ocsp_req_t REQ, gnutls_digest_algorithm_t DIGEST, const gnutls_datum_t * ISSUER_NAME_HASH, const gnutls_datum_t * ISSUER_KEY_HASH, const gnutls_datum_t * SERIAL_NUMBER) REQ: should contain a 'gnutls_ocsp_req_t' type DIGEST: hash algorithm, a 'gnutls_digest_algorithm_t' value ISSUER_NAME_HASH: hash of issuer's DN ISSUER_KEY_HASH: hash of issuer's public key SERIAL_NUMBER: serial number of certificate to check This function will add another request to the OCSP request for a particular certificate having the issuer name hash of 'issuer_name_hash' and issuer key hash of 'issuer_key_hash' (both hashed using 'digest' ) and serial number 'serial_number' . The information needed corresponds to the CertID structure: CertID ::= SEQUENCE { hashAlgorithm AlgorithmIdentifier, issuerNameHash OCTET STRING, - Hash of Issuer's DN issuerKeyHash OCTET STRING, - Hash of Issuers public key serialNumber CertificateSerialNumber } *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error code is returned. gnutls_ocsp_req_deinit ---------------------- -- Function: void gnutls_ocsp_req_deinit (gnutls_ocsp_req_t REQ) REQ: The data to be deinitialized This function will deinitialize a OCSP request structure. gnutls_ocsp_req_export ---------------------- -- Function: int gnutls_ocsp_req_export (gnutls_ocsp_req_const_t REQ, gnutls_datum_t * DATA) REQ: Holds the OCSP request DATA: newly allocate buffer holding DER encoded OCSP request This function will export the OCSP request to DER format. *Returns:* In case of failure a negative error code will be returned, and 0 on success. gnutls_ocsp_req_get_cert_id --------------------------- -- Function: int gnutls_ocsp_req_get_cert_id (gnutls_ocsp_req_const_t REQ, unsigned INDX, gnutls_digest_algorithm_t * DIGEST, gnutls_datum_t * ISSUER_NAME_HASH, gnutls_datum_t * ISSUER_KEY_HASH, gnutls_datum_t * SERIAL_NUMBER) REQ: should contain a 'gnutls_ocsp_req_t' type INDX: Specifies which extension OID to get. Use (0) to get the first one.

The information returned corresponds to the CertID structure: CertID ::= SEQUENCE { hashAlgorithm AlgorithmIdentifier, issuerNameHash OCTET STRING, - Hash of Issuer's DN issuerKeyHash OCTET STRING, - Hash of Issuers public key serialNumber CertificateSerialNumber } Each of the pointers to output variables may be NULL to indicate that the caller is not interested in that value. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error code is returned. If you have reached the last CertID available 'GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE' will be returned. gnutls_ocsp_req_get_extension ----------------------------- -- Function: int gnutls_ocsp_req_get_extension (gnutls_ocsp_req_const_t REQ, unsigned INDX, gnutls_datum_t * OID, unsigned int * CRITICAL, gnutls_datum_t * DATA) REQ: should contain a 'gnutls_ocsp_req_t' type INDX: Specifies which extension OID to get. Use (0) to get the first one. OID: will hold newly allocated buffer with OID of extension, may be NULL CRITICAL: output variable with critical flag, may be NULL. DATA: will hold newly allocated buffer with extension data, may be NULL This function will return all information about the requested extension in the OCSP request. The information returned is the OID, the critical flag, and the data itself. The extension OID will be stored as a string. Any of 'oid' , 'critical' , and 'data' may be NULL which means that the caller is not interested in getting that information back. The caller needs to deallocate memory by calling 'gnutls_free()' on 'oid' ->data and 'data' ->data. Since 3.7.0 'oid' ->size does not account for the terminating null byte. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error code is returned. If you have reached the last extension available 'GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE' will be returned. gnutls_ocsp_req_get_nonce ------------------------- -- Function: int gnutls_ocsp_req_get_nonce (gnutls_ocsp_req_const_t REQ, unsigned int * CRITICAL, gnutls_datum_t * NONCE) REQ: should contain a 'gnutls_ocsp_req_t' type CRITICAL: whether nonce extension is marked critical, or NULL NONCE: will hold newly allocated buffer with nonce data This function will return the OCSP request nonce extension data.

This function will pretty print a OCSP request, suitable for display to a human. If the format is 'GNUTLS_OCSP_PRINT_FULL' then all fields of the request will be output, on multiple lines. The output 'out' ->data needs to be deallocate using 'gnutls_free()' . *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. gnutls_ocsp_req_randomize_nonce ------------------------------- -- Function: int gnutls_ocsp_req_randomize_nonce (gnutls_ocsp_req_t REQ) REQ: should contain a 'gnutls_ocsp_req_t' type This function will add or update an nonce extension to the OCSP request with a newly generated random value. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error code is returned. gnutls_ocsp_req_set_extension ----------------------------- -- Function: int gnutls_ocsp_req_set_extension (gnutls_ocsp_req_t REQ, const char * OID, unsigned int CRITICAL, const gnutls_datum_t * DATA) REQ: should contain a 'gnutls_ocsp_req_t' type OID: buffer with OID of extension as a string. CRITICAL: critical flag, normally false. DATA: the extension data This function will add an extension to the OCSP request. Calling this function multiple times for the same OID will overwrite values from earlier calls. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error code is returned. gnutls_ocsp_req_set_nonce ------------------------- -- Function: int gnutls_ocsp_req_set_nonce (gnutls_ocsp_req_t REQ, unsigned int CRITICAL, const gnutls_datum_t * NONCE) REQ: should contain a 'gnutls_ocsp_req_t' type CRITICAL: critical flag, normally false.

Use (0) to get the first one. CRT: The certificate to check This function will check whether the OCSP response is about the provided certificate. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error code is returned. *Since:* 3.1.3 gnutls_ocsp_resp_deinit ----------------------- -- Function: void gnutls_ocsp_resp_deinit (gnutls_ocsp_resp_t RESP) RESP: The data to be deinitialized This function will deinitialize a OCSP response structure. gnutls_ocsp_resp_export ----------------------- -- Function: int gnutls_ocsp_resp_export (gnutls_ocsp_resp_const_t RESP, gnutls_datum_t * DATA) RESP: Holds the OCSP response DATA: newly allocate buffer holding DER encoded OCSP response This function will export the OCSP response to DER format. *Returns:* In case of failure a negative error code will be returned, and 0 on success. gnutls_ocsp_resp_export2 ------------------------ -- Function: int gnutls_ocsp_resp_export2 (gnutls_ocsp_resp_const_t RESP, gnutls_datum_t * DATA, gnutls_x509_crt_fmt_t FMT) RESP: Holds the OCSP response DATA: newly allocate buffer holding DER or PEM encoded OCSP response FMT: DER or PEM This function will export the OCSP response to DER or PEM format. *Returns:* In case of failure a negative error code will be returned, and 0 on success. *Since:* 3.6.3 gnutls_ocsp_resp_get_certs -------------------------- -- Function: int gnutls_ocsp_resp_get_certs (gnutls_ocsp_resp_const_t RESP, gnutls_x509_crt_t ** CERTS, size_t * NCERTS) RESP: should contain a 'gnutls_ocsp_resp_t' type CERTS: newly allocated array with 'gnutls_x509_crt_t' certificates NCERTS: output variable with number of allocated certs. This function will extract the X.509 certificates found in the Basic OCSP Response. The 'certs' output variable will hold a newly allocated zero-terminated array with X.509 certificates. Every certificate in the array needs to be de-allocated with 'gnutls_x509_crt_deinit()' and the array itself must be freed using 'gnutls_free()' . Both the 'certs' and 'ncerts' variables may be NULL. Then the function will work as normal but will not return the NULL:d information. This can be used to get the number of certificates only, or to just get the certificate array without its size. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. gnutls_ocsp_resp_get_extension ------------------------------ -- Function: int gnutls_ocsp_resp_get_extension (gnutls_ocsp_resp_const_t RESP, unsigned INDX, gnutls_datum_t * OID, unsigned int * CRITICAL, gnutls_datum_t * DATA) RESP: should contain a 'gnutls_ocsp_resp_t' type INDX: Specifies which extension OID to get. Use (0) to get the first one. OID: will hold newly allocated buffer with OID of extension, may be NULL CRITICAL: output variable with critical flag, may be NULL. DATA: will hold newly allocated buffer with extension data, may be NULL This function will return all information about the requested extension in the OCSP response. The information returned is the OID, the critical flag, and the data itself. The extension OID will be stored as a string. Any of 'oid' , 'critical' , and 'data' may be NULL which means that the caller is not interested in getting that information back. The caller needs to deallocate memory by calling 'gnutls_free()' on 'oid' ->data and 'data' ->data. Since 3.7.0 'oid' ->size does not account for the terminating null byte. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error code is returned. If you have reached the last extension available 'GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE' will be returned. gnutls_ocsp_resp_get_nonce -------------------------- -- Function: int gnutls_ocsp_resp_get_nonce (gnutls_ocsp_resp_const_t RESP, unsigned int * CRITICAL, gnutls_datum_t * NONCE) RESP: should contain a 'gnutls_ocsp_resp_t' type CRITICAL: whether nonce extension is marked critical NONCE: will hold newly allocated buffer with nonce data This function will return the Basic OCSP Response nonce extension data. The caller needs to deallocate memory by calling 'gnutls_free()' on 'nonce' ->data. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error code is returned. gnutls_ocsp_resp_get_produced ----------------------------- -- Function: time_t gnutls_ocsp_resp_get_produced (gnutls_ocsp_resp_const_t RESP) RESP: should contain a 'gnutls_ocsp_resp_t' type This function will return the time when the OCSP response was signed. *Returns:* signing time, or (time_t)-1 on error. gnutls_ocsp_resp_get_responder ------------------------------ -- Function: int gnutls_ocsp_resp_get_responder (gnutls_ocsp_resp_const_t RESP, gnutls_datum_t * DN) RESP: should contain a 'gnutls_ocsp_resp_t' type DN: newly allocated buffer with name This function will extract the name of the Basic OCSP Response in the provided buffer. The name will be in the form "C=xxxx,O=yyyy,CN=zzzz" as described in RFC2253. The output string will be ASCII or UTF-8 encoded, depending on the certificate data. If the responder ID is not a name but a hash, this function will return zero and the 'dn' elements will be set to 'NULL' . The caller needs to deallocate memory by calling 'gnutls_free()' on 'dn' ->data. This function does not output a fully RFC4514 compliant string, if that is required see 'gnutls_ocsp_resp_get_responder2()' . *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error code is returned. When no data exist it will return success and set 'dn' elements to zero. gnutls_ocsp_resp_get_responder2 ------------------------------- -- Function: int gnutls_ocsp_resp_get_responder2 (gnutls_ocsp_resp_const_t RESP, gnutls_datum_t * DN, unsigned FLAGS) RESP: should contain a 'gnutls_ocsp_resp_t' type DN: newly allocated buffer with name FLAGS: zero or 'GNUTLS_X509_DN_FLAG_COMPAT' This function will extract the name of the Basic OCSP Response in the provided buffer. The name will be in the form "C=xxxx,O=yyyy,CN=zzzz" as described in RFC2253. The output string will be ASCII or UTF-8 encoded, depending on the certificate data. If the responder ID is not a name but a hash, this function will return zero and the 'dn' elements will be set to 'NULL' . The caller needs to deallocate memory by calling 'gnutls_free()' on 'dn' ->data. When the flag 'GNUTLS_X509_DN_FLAG_COMPAT' is specified, the output format will match the format output by previous to 3.5.6 versions of GnuTLS which was not not fully RFC4514-compliant. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error code is returned. When no data exist it will return 'GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE' . gnutls_ocsp_resp_get_responder_raw_id ------------------------------------- -- Function: int gnutls_ocsp_resp_get_responder_raw_id (gnutls_ocsp_resp_const_t RESP, unsigned TYPE, gnutls_datum_t * RAW) RESP: should contain a 'gnutls_ocsp_resp_t' type TYPE: should be 'GNUTLS_OCSP_RESP_ID_KEY' or 'GNUTLS_OCSP_RESP_ID_DN' RAW: newly allocated buffer with the raw ID This function will extract the raw key (or DN) ID of the Basic OCSP Response in the provided buffer. If the responder ID is not a key ID then this function will return 'GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE' . The caller needs to deallocate memory by calling 'gnutls_free()' on 'dn' ->data. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error code is returned. gnutls_ocsp_resp_get_response ----------------------------- -- Function: int gnutls_ocsp_resp_get_response (gnutls_ocsp_resp_const_t RESP, gnutls_datum_t * RESPONSE_TYPE_OID, gnutls_datum_t * RESPONSE) RESP: should contain a 'gnutls_ocsp_resp_t' type RESPONSE_TYPE_OID: newly allocated output buffer with response type OID RESPONSE: newly allocated output buffer with DER encoded response This function will extract the response type OID in and the response data from an OCSP response. Normally the 'response_type_oid' is always "1.3.6.1.5.5.7.48.1.1" which means the 'response' should be decoded as a Basic OCSP Response, but technically other response types could be used. This function is typically only useful when you want to extract the response type OID of an response for diagnostic purposes. Otherwise 'gnutls_ocsp_resp_import()' will decode the basic OCSP response part and the caller need not worry about that aspect. Since 3.7.0 'response_type_oid' ->size does not account for the terminating null byte. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. gnutls_ocsp_resp_get_signature ------------------------------ -- Function: int gnutls_ocsp_resp_get_signature (gnutls_ocsp_resp_const_t RESP, gnutls_datum_t * SIG) RESP: should contain a 'gnutls_ocsp_resp_t' type SIG: newly allocated output buffer with signature data This function will extract the signature field of a OCSP response. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. gnutls_ocsp_resp_get_signature_algorithm ---------------------------------------- -- Function: int gnutls_ocsp_resp_get_signature_algorithm (gnutls_ocsp_resp_const_t RESP) RESP: should contain a 'gnutls_ocsp_resp_t' type This function will return a value of the 'gnutls_sign_algorithm_t' enumeration that is the signature algorithm that has been used to sign the OCSP response. *Returns:* a 'gnutls_sign_algorithm_t' value, or a negative error code on error. gnutls_ocsp_resp_get_single --------------------------- -- Function: int gnutls_ocsp_resp_get_single (gnutls_ocsp_resp_const_t RESP, unsigned INDX, gnutls_digest_algorithm_t * DIGEST, gnutls_datum_t * ISSUER_NAME_HASH, gnutls_datum_t * ISSUER_KEY_HASH, gnutls_datum_t * SERIAL_NUMBER, unsigned int * CERT_STATUS, time_t * THIS_UPDATE, time_t * NEXT_UPDATE, time_t * REVOCATION_TIME, unsigned int * REVOCATION_REASON) RESP: should contain a 'gnutls_ocsp_resp_t' type INDX: Specifies response number to get. Use (0) to get the first one. DIGEST: output variable with 'gnutls_digest_algorithm_t' hash algorithm ISSUER_NAME_HASH: output buffer with hash of issuer's DN ISSUER_KEY_HASH: output buffer with hash of issuer's public key SERIAL_NUMBER: output buffer with serial number of certificate to check CERT_STATUS: a certificate status, a 'gnutls_ocsp_cert_status_t' enum. THIS_UPDATE: time at which the status is known to be correct. NEXT_UPDATE: when newer information will be available, or (time_t)-1 if unspecified REVOCATION_TIME: when 'cert_status' is 'GNUTLS_OCSP_CERT_REVOKED' , holds time of revocation. REVOCATION_REASON: revocation reason, a 'gnutls_x509_crl_reason_t' enum. This function will return the certificate information of the 'indx' 'ed response in the Basic OCSP Response 'resp' . The information returned corresponds to the OCSP SingleResponse structure except the final singleExtensions. Each of the pointers to output variables may be NULL to indicate that the caller is not interested in that value. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error code is returned. If you have reached the last CertID available 'GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE' will be returned. gnutls_ocsp_resp_get_status --------------------------- -- Function: int gnutls_ocsp_resp_get_status (gnutls_ocsp_resp_const_t RESP) RESP: should contain a 'gnutls_ocsp_resp_t' type This function will return the status of a OCSP response, an 'gnutls_ocsp_resp_status_t' enumeration. *Returns:* status of OCSP request as a 'gnutls_ocsp_resp_status_t' , or a negative error code on error. gnutls_ocsp_resp_get_version ---------------------------- -- Function: int gnutls_ocsp_resp_get_version (gnutls_ocsp_resp_const_t RESP) RESP: should contain a 'gnutls_ocsp_resp_t' type This function will return the version of the Basic OCSP Response. Typically this is always 1 indicating version 1. *Returns:* version of Basic OCSP response, or a negative error code on error. gnutls_ocsp_resp_import ----------------------- -- Function: int gnutls_ocsp_resp_import (gnutls_ocsp_resp_t RESP, const gnutls_datum_t * DATA) RESP: The data to store the parsed response. DATA: DER encoded OCSP response. This function will convert the given DER encoded OCSP response to the native 'gnutls_ocsp_resp_t' format. It also decodes the Basic OCSP Response part, if any. The output will be stored in 'resp' . *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. gnutls_ocsp_resp_import2 ------------------------ -- Function: int gnutls_ocsp_resp_import2 (gnutls_ocsp_resp_t RESP, const gnutls_datum_t * DATA, gnutls_x509_crt_fmt_t FMT) RESP: The data to store the parsed response. DATA: DER or PEM encoded OCSP response. FMT: DER or PEM This function will convert the given OCSP response to the native 'gnutls_ocsp_resp_t' format. It also decodes the Basic OCSP Response part, if any. The output will be stored in 'resp' . *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. *Since:* 3.6.3 gnutls_ocsp_resp_init --------------------- -- Function: int gnutls_ocsp_resp_init (gnutls_ocsp_resp_t * RESP) RESP: A pointer to the type to be initialized This function will initialize an OCSP response structure. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. gnutls_ocsp_resp_list_import2 ----------------------------- -- Function: int gnutls_ocsp_resp_list_import2 (gnutls_ocsp_resp_t ** OCSPS, unsigned int * SIZE, const gnutls_datum_t * RESP_DATA, gnutls_x509_crt_fmt_t FORMAT, unsigned int FLAGS) OCSPS: Will hold the parsed OCSP response list. SIZE: It will contain the size of the list. RESP_DATA: The PEM encoded OCSP list. FORMAT: One of 'GNUTLS_X509_FMT_PEM' or 'GNUTLS_X509_FMT_DER' FLAGS: must be (0) or an OR'd sequence of gnutls_certificate_import_flags. This function will convert the given PEM encoded OCSP response list to the native gnutls_ocsp_resp_t format. The output will be stored in 'ocsps' which will be allocated and initialized. The OCSP responses should have a header of "OCSP RESPONSE". To deinitialize responses, you need to deinitialize each 'gnutls_ocsp_resp_t' structure independently, and use 'gnutls_free()' at 'ocsps' . In PEM files, when no OCSP responses are detected 'GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE' will be returned. *Returns:* the number of responses read or a negative error value. *Since:* 3.6.3 gnutls_ocsp_resp_print ---------------------- -- Function: int gnutls_ocsp_resp_print (gnutls_ocsp_resp_const_t RESP, gnutls_ocsp_print_formats_t FORMAT, gnutls_datum_t * OUT) RESP: The data to be printed FORMAT: Indicate the format to use OUT: Newly allocated datum with (0) terminated string. This function will pretty print a OCSP response, suitable for display to a human. If the format is 'GNUTLS_OCSP_PRINT_FULL' then all fields of the response will be output, on multiple lines. The output 'out' ->data needs to be deallocate using 'gnutls_free()' . *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. gnutls_ocsp_resp_verify ----------------------- -- Function: int gnutls_ocsp_resp_verify (gnutls_ocsp_resp_const_t RESP, gnutls_x509_trust_list_t TRUSTLIST, unsigned int * VERIFY, unsigned int FLAGS) RESP: should contain a 'gnutls_ocsp_resp_t' type TRUSTLIST: trust anchors as a 'gnutls_x509_trust_list_t' type VERIFY: output variable with verification status, an 'gnutls_ocsp_verify_reason_t' FLAGS: verification flags from 'gnutls_certificate_verify_flags' Verify signature of the Basic OCSP Response against the public key in the certificate of a trusted signer. The 'trustlist' should be populated with trust anchors. The function will extract the signer certificate from the Basic OCSP Response and will verify it against the 'trustlist' . A trusted signer is a certificate that is either in 'trustlist' , or it is signed directly by a certificate in 'trustlist' and has the id-ad-ocspSigning Extended Key Usage bit set. The output 'verify' variable will hold verification status codes (e.g., 'GNUTLS_OCSP_VERIFY_SIGNER_NOT_FOUND' , 'GNUTLS_OCSP_VERIFY_INSECURE_ALGORITHM' ) which are only valid if the function returned 'GNUTLS_E_SUCCESS' .

This function will return information about the PKCS 11 token such as the label, id, etc. When output is text, a null terminated string is written to 'output' and its string length is written to 'output_size' (without null terminator). If the buffer is too small, 'output_size' will contain the expected buffer size (with null terminator for text) and return 'GNUTLS_E_SHORT_MEMORY_BUFFER' . *Returns:* 'GNUTLS_E_SUCCESS' (0) on success or a negative error code on error. *Since:* 2.12.0 gnutls_pkcs11_token_get_mechanism --------------------------------- -- Function: int gnutls_pkcs11_token_get_mechanism (const char * URL, unsigned int IDX, unsigned long * MECHANISM) URL: should contain a PKCS 11 URL IDX: The index of the mechanism MECHANISM: The PKCS '11' mechanism ID This function will return the names of the supported mechanisms by the token.

Otherwise it should match the officer's PIN. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. gnutls_pkcs11_token_set_pin --------------------------- -- Function: int gnutls_pkcs11_token_set_pin (const char * TOKEN_URL, const char * OLDPIN, const char * NEWPIN, unsigned int FLAGS) TOKEN_URL: A PKCS '11' URL specifying a token OLDPIN: old user's PIN NEWPIN: new user's PIN FLAGS: one of 'gnutls_pin_flag_t' . This function will modify or set a user or administrator's PIN for the given token. If it is called to set a PIN for first time the oldpin must be 'NULL' . When setting the admin's PIN with the 'GNUTLS_PIN_SO' flag, the 'oldpin' value must be provided (this requirement is relaxed after GnuTLS 3.6.5 since which the PIN will be requested if missing). *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. gnutls_pkcs11_type_get_name --------------------------- -- Function: const char * gnutls_pkcs11_type_get_name (gnutls_pkcs11_obj_type_t TYPE) TYPE: Holds the PKCS 11 object type, a 'gnutls_pkcs11_obj_type_t' .

Note that bits in TPM is quantized value. If the input value is not one of the allowed values, then it will be quantized to one of 512, 1024, 2048, 4096, 8192 and 16384. Allowed flags are: *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. *Since:* 3.1.0  File: gnutls.info, Node: Abstract key API, Next: Socket specific API, Prev: TPM API, Up: API reference E.9 Abstract key API ==================== The following functions are to be used for abstract key handling. Their prototypes lie in 'gnutls/abstract.h'. gnutls_certificate_set_key -------------------------- -- Function: int gnutls_certificate_set_key (gnutls_certificate_credentials_t RES, const char ** NAMES, int NAMES_SIZE, gnutls_pcert_st * PCERT_LIST, int PCERT_LIST_SIZE, gnutls_privkey_t KEY) RES: is a 'gnutls_certificate_credentials_t' type. NAMES: is an array of DNS names belonging to the public-key (NULL if none) NAMES_SIZE: holds the size of the names list PCERT_LIST: contains a certificate list (chain) or raw public-key PCERT_LIST_SIZE: holds the size of the certificate list KEY: is a 'gnutls_privkey_t' key corresponding to the first public-key in pcert_list This function sets a public/private key pair in the gnutls_certificate_credentials_t type. The given public key may be encapsulated in a certificate or can be given as a raw key. This function may be called more than once, in case multiple key pairs exist for the server. For clients that want to send more than their own end- entity certificate (e.g., also an intermediate CA cert), the full certificate chain must be provided in 'pcert_list' . Note that the 'key' will become part of the credentials structure and must not be deallocated. It will be automatically deallocated when the 'res' structure is deinitialized. If this function fails, the 'res' structure is at an undefined state and it must not be reused to load other keys or certificates. Note that, this function by default returns zero on success and a negative value on error. Since 3.5.6, when the flag 'GNUTLS_CERTIFICATE_API_V2' is set using 'gnutls_certificate_set_flags()' it returns an index (greater or equal to zero). That index can be used for other functions to refer to the added key-pair. Since GnuTLS 3.6.6 this function also handles raw public keys. *Returns:* On success this functions returns zero, and otherwise a negative value on error (see above for modifying that behavior). *Since:* 3.0 gnutls_certificate_set_retrieve_function2 ----------------------------------------- -- Function: void gnutls_certificate_set_retrieve_function2 (gnutls_certificate_credentials_t CRED, gnutls_certificate_retrieve_function2 * FUNC) CRED: is a 'gnutls_certificate_credentials_t' type. FUNC: is the callback function This function sets a callback to be called in order to retrieve the certificate to be used in the handshake. The callback will take control only if a certificate is requested by the peer. The callback's function prototype is: int (*callback)(gnutls_session_t, const gnutls_datum_t* req_ca_dn, int nreqs, const gnutls_pk_algorithm_t* pk_algos, int pk_algos_length, gnutls_pcert_st** pcert, unsigned int *pcert_length, gnutls_privkey_t * pkey); 'req_ca_dn' is only used in X.509 certificates. Contains a list with the CA names that the server considers trusted. This is a hint and typically the client should send a certificate that is signed by one of these CAs. These names, when available, are DER encoded. To get a more meaningful value use the function 'gnutls_x509_rdn_get()' . 'pk_algos' contains a list with server's acceptable public key algorithms. The certificate returned should support the server's given algorithms. 'pcert' should contain a single certificate and public key or a list of them. 'pcert_length' is the size of the previous list. 'pkey' is the private key. If the callback function is provided then gnutls will call it, in the handshake, after the certificate request message has been received. All the provided by the callback values will not be released or modified by gnutls. In server side pk_algos and req_ca_dn are NULL. The callback function should set the certificate list to be sent, and return 0 on success. If no certificate was selected then the number of certificates should be set to zero. The value (-1) indicates error and the handshake will be terminated. If both certificates are set in the credentials and a callback is available, the callback takes predence. *Since:* 3.0 gnutls_certificate_set_retrieve_function3 ----------------------------------------- -- Function: void gnutls_certificate_set_retrieve_function3 (gnutls_certificate_credentials_t CRED, gnutls_certificate_retrieve_function3 * FUNC) CRED: is a 'gnutls_certificate_credentials_t' type. FUNC: is the callback function This function sets a callback to be called in order to retrieve the certificate and OCSP responses to be used in the handshake. 'func' will be called only if the peer requests a certificate either during handshake or during post-handshake authentication. The callback's function prototype is defined in 'abstract.h': int gnutls_certificate_retrieve_function3( gnutls_session_t, const struct gnutls_cert_retr_st *info, gnutls_pcert_st **certs, unsigned int *certs_length, gnutls_ocsp_data_st **ocsp, unsigned int *ocsp_length, gnutls_privkey_t *privkey, unsigned int *flags); The info field of the callback contains: 'req_ca_dn' which is a list with the CA names that the server considers trusted. This is a hint and typically the client should send a certificate that is signed by one of these CAs. These names, when available, are DER encoded. To get a more meaningful value use the function 'gnutls_x509_rdn_get()' . 'pk_algos' contains a list with server's acceptable public key algorithms. The certificate returned should support the server's given algorithms. The callback should fill-in the following values: 'certs' should contain an allocated list of certificates and public keys. 'certs_length' is the size of the previous list. 'ocsp' should contain an allocated list of OCSP responses. 'ocsp_length' is the size of the previous list. 'privkey' is the private key. If flags in the callback are set to 'GNUTLS_CERT_RETR_DEINIT_ALL' then all provided values must be allocated using 'gnutls_malloc()' , and will be released by gnutls; otherwise they will not be touched by gnutls. The callback function should set the certificate and OCSP response list to be sent, and return 0 on success. If no certificates are available, the 'certs_length' and 'ocsp_length' should be set to zero. The return value (-1) indicates error and the handshake will be terminated. If both certificates are set in the credentials and a callback is available, the callback takes predence. Raw public-keys: In case raw public-keys are negotiated as certificate type, certificates that would normally hold the public-key material are not available. In that case, 'certs' contains an allocated list with only the public key. Since there is no certificate, there is also no certificate status. Therefore, OCSP information should not be set. *Since:* 3.6.3 gnutls_pcert_deinit ------------------- -- Function: void gnutls_pcert_deinit (gnutls_pcert_st * PCERT) PCERT: The structure to be deinitialized This function will deinitialize a pcert structure. *Since:* 3.0 gnutls_pcert_export_openpgp --------------------------- -- Function: int gnutls_pcert_export_openpgp (gnutls_pcert_st * PCERT, gnutls_openpgp_crt_t * CRT) PCERT: The pcert structure.

The structure must be deinitialized afterwards using 'gnutls_pcert_deinit()' . Note that the caller is responsible for freeing 'rawpubkey' . All necessary values will be copied into 'pcert' . Key usage (as defined by X.509 extension (2.5.29.15)) can be explicitly set because there is no certificate structure around the key to define this value. See for more info 'gnutls_x509_crt_get_key_usage()' . *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. *Since:* 3.6.6 gnutls_pcert_import_x509 ------------------------ -- Function: int gnutls_pcert_import_x509 (gnutls_pcert_st * PCERT, gnutls_x509_crt_t CRT, unsigned int FLAGS) PCERT: The pcert structure CRT: The certificate to be imported FLAGS: zero for now This convenience function will import the given certificate to a 'gnutls_pcert_st' structure.

BITS: the size of the parameters to generate FLAGS: Must be zero or flags from 'gnutls_privkey_flags_t' . This function will generate a random private key. Note that this function must be called on an initialized private key. The flag 'GNUTLS_PRIVKEY_FLAG_PROVABLE' instructs the key generation process to use algorithms like Shawe-Taylor (from FIPS PUB186-4) which generate provable parameters out of a seed for RSA and DSA keys. See 'gnutls_privkey_generate2()' for more information. Note that when generating an elliptic curve key, the curve can be substituted in the place of the bits parameter using the 'GNUTLS_CURVE_TO_BITS()' macro. The input to the macro is any curve from 'gnutls_ecc_curve_t' . For DSA keys, if the subgroup size needs to be specified check the 'GNUTLS_SUBGROUP_TO_BITS()' macro. It is recommended to do not set the number of 'bits' directly, use 'gnutls_sec_param_to_pk_bits()' instead . See also 'gnutls_privkey_generate2()' . *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. *Since:* 3.3.0 gnutls_privkey_generate2 ------------------------ -- Function: int gnutls_privkey_generate2 (gnutls_privkey_t PKEY, gnutls_pk_algorithm_t ALGO, unsigned int BITS, unsigned int FLAGS, const gnutls_keygen_data_st * DATA, unsigned DATA_SIZE) PKEY: The private key ALGO: is one of the algorithms in 'gnutls_pk_algorithm_t' .

DATA_SIZE: The number of 'data' available. This function will generate a random private key. Note that this function must be called on an initialized private key. The flag 'GNUTLS_PRIVKEY_FLAG_PROVABLE' instructs the key generation process to use algorithms like Shawe-Taylor (from FIPS PUB186-4) which generate provable parameters out of a seed for RSA and DSA keys. On DSA keys the PQG parameters are generated using the seed, while on RSA the two primes. To specify an explicit seed (by default a random seed is used), use the 'data' with a 'GNUTLS_KEYGEN_SEED' type. Note that when generating an elliptic curve key, the curve can be substituted in the place of the bits parameter using the 'GNUTLS_CURVE_TO_BITS()' macro. To export the generated keys in memory or in files it is recommended to use the PKCS'8' form as it can handle all key types, and can store additional parameters such as the seed, in case of provable RSA or DSA keys. Generated keys can be exported in memory using 'gnutls_privkey_export_x509()' , and then with 'gnutls_x509_privkey_export2_pkcs8()' . If key generation is part of your application, avoid setting the number of bits directly, and instead use 'gnutls_sec_param_to_pk_bits()' . That way the generated keys will adapt to the security levels of the underlying GnuTLS library. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. *Since:* 3.5.0 gnutls_privkey_get_pk_algorithm ------------------------------- -- Function: int gnutls_privkey_get_pk_algorithm (gnutls_privkey_t KEY, unsigned int * BITS) KEY: should contain a 'gnutls_privkey_t' type BITS: If set will return the number of bits of the parameters (may be NULL) This function will return the public key algorithm of a private key and if possible will return a number of bits that indicates the security parameter of the key. *Returns:* a member of the 'gnutls_pk_algorithm_t' enumeration on success, or a negative error code on error. *Since:* 2.12.0 gnutls_privkey_get_seed ----------------------- -- Function: int gnutls_privkey_get_seed (gnutls_privkey_t KEY, gnutls_digest_algorithm_t * DIGEST, void * SEED, size_t * SEED_SIZE) KEY: should contain a 'gnutls_privkey_t' type DIGEST: if non-NULL it will contain the digest algorithm used for key generation (if applicable) SEED: where seed will be copied to SEED_SIZE: originally holds the size of 'seed' , will be updated with actual size This function will return the seed that was used to generate the given private key. That function will succeed only if the key was generated as a provable key. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. *Since:* 3.5.0 gnutls_privkey_get_spki ----------------------- -- Function: int gnutls_privkey_get_spki (gnutls_privkey_t PRIVKEY, gnutls_x509_spki_t SPKI, unsigned int FLAGS) PRIVKEY: a public key of type 'gnutls_privkey_t' SPKI: a SubjectPublicKeyInfo structure of type 'gnutls_privkey_spki_t' FLAGS: must be zero This function will return the public key information if available.

The provided structure and callback functions must be valid throughout the lifetime of the process. The registration of an existing URL type will fail with 'GNUTLS_E_INVALID_REQUEST' . Since GnuTLS 3.5.0 this function can be used to override the builtin URLs.

This must be the last step in a certificate generation since all the previously set parameters are now signed. A known limitation of this function is, that a newly-signed certificate will not be fully functional (e.g., for signature verification), until it is exported an re-imported. After GnuTLS 3.6.1 the value of 'dig' may be 'GNUTLS_DIG_UNKNOWN' , and in that case, a suitable but reasonable for the key algorithm will be selected. *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. gnutls_x509_crt_set_pubkey -------------------------- -- Function: int gnutls_x509_crt_set_pubkey (gnutls_x509_crt_t CRT, gnutls_pubkey_t KEY) CRT: should contain a 'gnutls_x509_crt_t' type KEY: holds a public key This function will set the public parameters from the given public key to the certificate.

That means that TCP connection establishment and the transmission of the first TLS client hello packet are combined. The peer's address must be specified in 'connect_addr' and 'connect_addrlen' , and the socket specified by 'fd' should not be connected. TFO only works for TCP sockets of type AF_INET and AF_INET6. If the OS doesn't support TCP fast open this function will result to gnutls using 'connect()' transparently during the first write. *Note:* This function overrides all the transport callback functions. If this is undesirable, TCP Fast Open must be implemented on the user callback functions without calling this function. When using this function, transport callbacks must not be set, and 'gnutls_transport_set_ptr()' or 'gnutls_transport_set_int()' must not be called. On GNU/Linux TFO has to be enabled at the system layer, that is in /proc/sys/net/ipv4/tcp_fastopen, bit 0 has to be set.

The difference is that it accepts an error number returned by a gnutls function; In case of an unknown error a descriptive string is sent instead of 'NULL' . Error codes are always a negative error code. *Returns:* A string explaining the DANE error message. dane_verification_status_print ------------------------------ -- Function: int dane_verification_status_print (unsigned int STATUS, gnutls_datum_t * OUT, unsigned int FLAGS) STATUS: The status flags to be printed OUT: Newly allocated datum with (0) terminated string. FLAGS: should be zero This function will pretty print the status of a verification process - eg. the one obtained by 'dane_verify_crt()' . The output 'out' needs to be deallocated using 'gnutls_free()' . *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value. dane_verify_crt --------------- -- Function: int dane_verify_crt (dane_state_t S, const gnutls_datum_t * CHAIN, unsigned CHAIN_SIZE, gnutls_certificate_type_t CHAIN_TYPE, const char * HOSTNAME, const char * PROTO, unsigned int PORT, unsigned int SFLAGS, unsigned int VFLAGS, unsigned int * VERIFY) S: A DANE state structure (may be NULL) CHAIN: A certificate chain CHAIN_SIZE: The size of the chain CHAIN_TYPE: The type of the certificate chain HOSTNAME: The hostname associated with the chain PROTO: The protocol of the service connecting (e.g. tcp) PORT: The port of the service connecting (e.g. 443) SFLAGS: Flags for the initialization of 's' (if NULL) VFLAGS: Verification flags; an OR'ed list of 'dane_verify_flags_t' . VERIFY: An OR'ed list of 'dane_verify_status_t' . This function will verify the given certificate chain against the CA constrains and/or the certificate available via DANE. If no information via DANE can be obtained the flag 'DANE_VERIFY_NO_DANE_INFO' is set. If a DNSSEC signature is not available for the DANE record then the verify flag 'DANE_VERIFY_NO_DNSSEC_DATA' is set. Due to the many possible options of DANE, there is no single threat model countered. When notifying the user about DANE verification results it may be better to mention: DANE verification did not reject the certificate, rather than mentioning a successful DANE verication. Note that this function is designed to be run in addition to PKIX - certificate chain - verification. To be run independently the 'DANE_VFLAG_ONLY_CHECK_EE_USAGE' flag should be specified; then the function will check whether the key of the peer matches the key advertized in the DANE entry. *Returns:* a negative error code on error and 'DANE_E_SUCCESS' (0) when the DANE entries were successfully parsed, irrespective of whether they were verified (see 'verify' for that information). If no usable entries were encountered 'DANE_E_REQUESTED_DATA_NOT_AVAILABLE' will be returned. dane_verify_crt_raw ------------------- -- Function: int dane_verify_crt_raw (dane_state_t S, const gnutls_datum_t * CHAIN, unsigned CHAIN_SIZE, gnutls_certificate_type_t CHAIN_TYPE, dane_query_t R, unsigned int SFLAGS, unsigned int VFLAGS, unsigned int * VERIFY) S: A DANE state structure (may be NULL) CHAIN: A certificate chain CHAIN_SIZE: The size of the chain CHAIN_TYPE: The type of the certificate chain R: DANE data to check against SFLAGS: Flags for the initialization of 's' (if NULL) VFLAGS: Verification flags; an OR'ed list of 'dane_verify_flags_t' . VERIFY: An OR'ed list of 'dane_verify_status_t' . This is the low-level function of 'dane_verify_crt()' . See the high level function for documentation. This function does not perform any resolving, it utilizes cached entries from 'r' . *Returns:* a negative error code on error and 'DANE_E_SUCCESS' (0) when the DANE entries were successfully parsed, irrespective of whether they were verified (see 'verify' for that information). If no usable entries were encountered 'DANE_E_REQUESTED_DATA_NOT_AVAILABLE' will be returned. dane_verify_session_crt ----------------------- -- Function: int dane_verify_session_crt (dane_state_t S, gnutls_session_t SESSION, const char * HOSTNAME, const char * PROTO, unsigned int PORT, unsigned int SFLAGS, unsigned int VFLAGS, unsigned int * VERIFY) S: A DANE state structure (may be NULL) SESSION: A gnutls session HOSTNAME: The hostname associated with the chain PROTO: The protocol of the service connecting (e.g. tcp) PORT: The port of the service connecting (e.g. 443) SFLAGS: Flags for the initialization of 's' (if NULL) VFLAGS: Verification flags; an OR'ed list of 'dane_verify_flags_t' . VERIFY: An OR'ed list of 'dane_verify_status_t' . This function will verify session's certificate chain against the CA constrains and/or the certificate available via DANE. See 'dane_verify_crt()' for more information. This will not verify the chain for validity; unless the DANE verification is restricted to end certificates, this must be be performed separately using 'gnutls_certificate_verify_peers3()' . *Returns:* a negative error code on error and 'DANE_E_SUCCESS' (0) when the DANE entries were successfully parsed, irrespective of whether they were verified (see 'verify' for that information). If no usable entries were encountered 'DANE_E_REQUESTED_DATA_NOT_AVAILABLE' will be returned.

Copying contexts for Message Digests registered using 'gnutls_crypto_register_digest()' is not supported and will always result in an error. In addition to that, some of the Message Digest implementations do not support this operation. Applications should check the return value and provide a proper fallback. *Returns:* new Message Digest context or NULL in case of an error. *Since:* 3.6.9 gnutls_hash_deinit ------------------ -- Function: void gnutls_hash_deinit (gnutls_hash_hd_t HANDLE, void * DIGEST) HANDLE: is a 'gnutls_hash_hd_t' type DIGEST: is the output value of the hash This function will deinitialize all resources occupied by the given hash context. *Since:* 2.10.0 gnutls_hash_fast ---------------- -- Function: int gnutls_hash_fast (gnutls_digest_algorithm_t ALGORITHM, const void * PTEXT, size_t PTEXT_LEN, void * DIGEST) ALGORITHM: the hash algorithm to use PTEXT: the data to hash PTEXT_LEN: the length of data to hash DIGEST: is the output value of the hash This convenience function will hash the given data and return output on a single call. *Returns:* Zero or a negative error code on error. *Since:* 2.10.0 gnutls_hash_get_len ------------------- -- Function: unsigned gnutls_hash_get_len (gnutls_digest_algorithm_t ALGORITHM) ALGORITHM: the hash algorithm to use This function will return the length of the output data of the given hash algorithm. *Returns:* The length or zero on error. *Since:* 2.10.0 gnutls_hash_init ---------------- -- Function: int gnutls_hash_init (gnutls_hash_hd_t * DIG, gnutls_digest_algorithm_t ALGORITHM) DIG: is a 'gnutls_hash_hd_t' type ALGORITHM: the hash algorithm to use This function will initialize an context that can be used to produce a Message Digest of data.

May be NULL. REALLOC_FUNC: A realloc function FREE_FUNC: The function that frees allocated data. Must accept a NULL pointer. *Deprecated:* since 3.3.0 it is no longer possible to replace the internally used memory allocation functions This is the function where you set the memory allocation functions gnutls is going to use. By default the libc's allocation functions ('malloc()' , 'free()' ), are used by gnutls, to allocate both sensitive and not sensitive data. This function is provided to set the memory allocation functions to something other than the defaults This function must be called before 'gnutls_global_init()' is called. This function is not thread safe. gnutls_openpgp_privkey_sign_hash -------------------------------- -- Function: int gnutls_openpgp_privkey_sign_hash (gnutls_openpgp_privkey_t KEY, const gnutls_datum_t * HASH, gnutls_datum_t * SIGNATURE) KEY: Holds the key HASH: holds the data to be signed SIGNATURE: will contain newly allocated signature This function is no-op. *Returns:* 'GNUTLS_E_UNIMPLEMENTED_FEATURE' . gnutls_priority_compression_list -------------------------------- -- Function: int gnutls_priority_compression_list (gnutls_priority_t PCACHE, const unsigned int ** LIST) PCACHE: is a 'gnutls_priority_t' type.

May be 'NULL' . This function will read the certificate and return the appropriate digest algorithm to use for signing with this certificate. Some certificates (i.e. DSA might not be able to sign without the preferred algorithm). *Deprecated:* Please use 'gnutls_pubkey_get_preferred_hash_algorithm()' . *Returns:* the 0 if the hash algorithm is found. A negative error code is returned on error. *Since:* 2.12.0 gnutls_x509_privkey_sign_hash ----------------------------- -- Function: int gnutls_x509_privkey_sign_hash (gnutls_x509_privkey_t KEY, const gnutls_datum_t * HASH, gnutls_datum_t * SIGNATURE) KEY: a key HASH: holds the data to be signed SIGNATURE: will contain newly allocated signature This function will sign the given hash using the private key. Do not use this function directly unless you know what it is. Typical signing requires the data to be hashed and stored in special formats (e.g. BER Digest-Info for RSA). This API is provided only for backwards compatibility, and thus restricted to RSA, DSA and ECDSA key types. For other key types please use 'gnutls_privkey_sign_hash()' and 'gnutls_privkey_sign_data()' . *Returns:* On success, 'GNUTLS_E_SUCCESS' (0) is returned, otherwise a negative error value.

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. 0. PREAMBLE The purpose of this License is to make a manual, textbook, or other functional and useful document "free" in the sense of freedom: to assure everyone the effective freedom to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to get credit for their work, while not being considered responsible for modifications made by others. This License is a kind of "copyleft", which means that derivative works of the document must themselves be free in the same sense. It complements the GNU General Public License, which is a copyleft license designed for free software. We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals providing the same freedoms that the software does. But this License is not limited to software manuals; it can be used for any textual work, regardless of subject matter or whether it is published as a printed book. We recommend this License principally for works whose purpose is instruction or reference. 1. APPLICABILITY AND DEFINITIONS This License applies to any manual or other work, in any medium, that contains a notice placed by the copyright holder saying it can be distributed under the terms of this License. Such a notice grants a world-wide, royalty-free license, unlimited in duration, to use that work under the conditions stated herein. The "Document", below, refers to any such manual or work. Any member of the public is a licensee, and is addressed as "you". You accept the license if you copy, modify or distribute the work in a way requiring permission under copyright law. A "Modified Version" of the Document means any work containing the Document or a portion of it, either copied verbatim, or with modifications and/or translated into another language. A "Secondary Section" is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the Document to the Document's overall subject (or to related matters) and contains nothing that could fall directly within that overall subject. (Thus, if the Document is in part a textbook of mathematics, a Secondary Section may not explain any mathematics.) The relationship could be a matter of historical connection with the subject or with related matters, or of legal, commercial, philosophical, ethical or political position regarding them. The "Invariant Sections" are certain Secondary Sections whose titles are designated, as being those of Invariant Sections, in the notice that says that the Document is released under this License. If a section does not fit the above definition of Secondary then it is not allowed to be designated as Invariant. The Document may contain zero Invariant Sections. If the Document does not identify any Invariant Sections then there are none. The "Cover Texts" are certain short passages of text that are listed, as Front-Cover Texts or Back-Cover Texts, in the notice that says that the Document is released under this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at most 25 words. A "Transparent" copy of the Document means a machine-readable copy, represented in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup, or absence of markup, has been arranged to thwart or discourage subsequent modification by readers is not Transparent. An image format is not Transparent if used for any substantial amount of text. A copy that is not "Transparent" is called "Opaque". Examples of suitable formats for Transparent copies include plain ASCII without markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly available DTD, and standard-conforming simple HTML, PostScript or PDF designed for human modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque formats include proprietary formats that can be read and edited only by proprietary word processors, SGML or XML for which the DTD and/or processing tools are not generally available, and the machine-generated HTML, PostScript or PDF produced by some word processors for output purposes only. The "Title Page" means, for a printed book, the title page itself, plus such following pages as are needed to hold, legibly, the material this License requires to appear in the title page. For works in formats which do not have any title page as such, "Title Page" means the text near the most prominent appearance of the work's title, preceding the beginning of the body of the text. The "publisher" means any person or entity that distributes copies of the Document to the public. A section "Entitled XYZ" means a named subunit of the Document whose title either is precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another language. (Here XYZ stands for a specific section name mentioned below, such as "Acknowledgements", "Dedications", "Endorsements", or "History".) To "Preserve the Title" of such a section when you modify the Document means that it remains a section "Entitled XYZ" according to this definition. The Document may include Warranty Disclaimers next to the notice which states that this License applies to the Document. These Warranty Disclaimers are considered to be included by reference in this License, but only as regards disclaiming warranties: any other implication that these Warranty Disclaimers may have is void and has no effect on the meaning of this License. 2. VERBATIM COPYING You may copy and distribute the Document in any medium, either commercially or noncommercially, provided that this License, the copyright notices, and the license notice saying this License applies to the Document are reproduced in all copies, and that you add no other conditions whatsoever to those of this License. You may not use technical measures to obstruct or control the reading or further copying of the copies you make or distribute. However, you may accept compensation in exchange for copies. If you distribute a large enough number of copies you must also follow the conditions in section 3. You may also lend copies, under the same conditions stated above, and you may publicly display copies. 3. COPYING IN QUANTITY If you publish printed copies (or copies in media that commonly have printed covers) of the Document, numbering more than 100, and the Document's license notice requires Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both covers must also clearly and legibly identify you as the publisher of these copies. The front cover must present the full title with all words of the title equally prominent and visible. You may add other material on the covers in addition. Copying with changes limited to the covers, as long as they preserve the title of the Document and satisfy these conditions, can be treated as verbatim copying in other respects. If the required texts for either cover are too voluminous to fit legibly, you should put the first ones listed (as many as fit reasonably) on the actual cover, and continue the rest onto adjacent pages. If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option, you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of that edition to the public. It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a chance to provide you with an updated version of the Document. 4. MODIFICATIONS You may copy and distribute a Modified Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modified Version under precisely this License, with the Modified Version filling the role of the Document, thus licensing distribution and modification of the Modified Version to whoever possesses a copy of it. In addition, you must do these things in the Modified Version: A. Use in the Title Page (and on the covers, if any) a title distinct from that of the Document, and from those of previous versions (which should, if there were any, be listed in the History section of the Document). You may use the same title as a previous version if the original publisher of that version gives permission. B. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modifications in the Modified Version, together with at least five of the principal authors of the Document (all of its principal authors, if it has fewer than five), unless they release you from this requirement. C. State on the Title page the name of the publisher of the Modified Version, as the publisher. D. Preserve all the copyright notices of the Document. E. Add an appropriate copyright notice for your modifications adjacent to the other copyright notices. F. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modified Version under the terms of this License, in the form shown in the Addendum below. G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document's license notice. H. Include an unaltered copy of this License. I. Preserve the section Entitled "History", Preserve its Title, and add to it an item stating at least the title, year, new authors, and publisher of the Modified Version as given on the Title Page. If there is no section Entitled "History" in the Document, create one stating the title, year, authors, and publisher of the Document as given on its Title Page, then add an item describing the Modified Version as stated in the previous sentence. J. Preserve the network location, if any, given in the Document for public access to a Transparent copy of the Document, and likewise the network locations given in the Document for previous versions it was based on. These may be placed in the "History" section. You may omit a network location for a work that was published at least four years before the Document itself, or if the original publisher of the version it refers to gives permission. K. For any section Entitled "Acknowledgements" or "Dedications", Preserve the Title of the section, and preserve in the section all the substance and tone of each of the contributor acknowledgements and/or dedications given therein. L. Preserve all the Invariant Sections of the Document, unaltered in their text and in their titles. Section numbers or the equivalent are not considered part of the section titles. M. Delete any section Entitled "Endorsements". Such a section may not be included in the Modified Version. N. Do not retitle any existing section to be Entitled "Endorsements" or to conflict in title with any Invariant Section. O. Preserve any Warranty Disclaimers. If the Modified Version includes new front-matter sections or appendices that qualify as Secondary Sections and contain no material copied from the Document, you may at your option designate some or all of these sections as invariant. To do this, add their titles to the list of Invariant Sections in the Modified Version's license notice. These titles must be distinct from any other section titles. You may add a section Entitled "Endorsements", provided it contains nothing but endorsements of your Modified Version by various parties--for example, statements of peer review or that the text has been approved by an organization as the authoritative definition of a standard. You may add a passage of up to five words as a Front-Cover Text, and a passage of up to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be added by (or through arrangements made by) any one entity. If the Document already includes a cover text for the same cover, previously added by you or by arrangement made by the same entity you are acting on behalf of, you may not add another; but you may replace the old one, on explicit permission from the previous publisher that added the old one. The author(s) and publisher(s) of the Document do not by this License give permission to use their names for publicity for or to assert or imply endorsement of any Modified Version. 5. COMBINING DOCUMENTS You may combine the Document with other documents released under this License, under the terms defined in section 4 above for modified versions, provided that you include in the combination all of the Invariant Sections of all of the original documents, unmodified, and list them all as Invariant Sections of your combined work in its license notice, and that you preserve all their Warranty Disclaimers. The combined work need only contain one copy of this License, and multiple identical Invariant Sections may be replaced with a single copy. If there are multiple Invariant Sections with the same name but different contents, make the title of each such section unique by adding at the end of it, in parentheses, the name of the original author or publisher of that section if known, or else a unique number. Make the same adjustment to the section titles in the list of Invariant Sections in the license notice of the combined work. In the combination, you must combine any sections Entitled "History" in the various original documents, forming one section Entitled "History"; likewise combine any sections Entitled "Acknowledgements", and any sections Entitled "Dedications". You must delete all sections Entitled "Endorsements." 6. COLLECTIONS OF DOCUMENTS You may make a collection consisting of the Document and other documents released under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the rules of this License for verbatim copying of each of the documents in all other respects. You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted document, and follow this License in all other respects regarding verbatim copying of that document. 7. AGGREGATION WITH INDEPENDENT WORKS A compilation of the Document or its derivatives with other separate and independent documents or works, in or on a volume of a storage or distribution medium, is called an "aggregate" if the copyright resulting from the compilation is not used to limit the legal rights of the compilation's users beyond what the individual works permit. When the Document is included in an aggregate, this License does not apply to the other works in the aggregate which are not themselves derivative works of the Document. If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document's Cover Texts may be placed on covers that bracket the Document within the aggregate, or the electronic equivalent of covers if the Document is in electronic form. Otherwise they must appear on printed covers that bracket the whole aggregate. 8. TRANSLATION Translation is considered a kind of modification, so you may distribute translations of the Document under the terms of section 4. Replacing Invariant Sections with translations requires special permission from their copyright holders, but you may include translations of some or all Invariant Sections in addition to the original versions of these Invariant Sections. You may include a translation of this License, and all the license notices in the Document, and any Warranty Disclaimers, provided that you also include the original English version of this License and the original versions of those notices and disclaimers. In case of a disagreement between the translation and the original version of this License or a notice or disclaimer, the original version will prevail. If a section in the Document is Entitled "Acknowledgements", "Dedications", or "History", the requirement (section 4) to Preserve its Title (section 1) will typically require changing the actual title. 9. TERMINATION You may not copy, modify, sublicense, or distribute the Document except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, or distribute it is void, and will automatically terminate your rights under this License. However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, receipt of a copy of some or all of the same material does not give you any rights to use it. 10. FUTURE REVISIONS OF THIS LICENSE The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. See . Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License "or any later version" applies to it, you have the option of following the terms and conditions either of that specified version or of any later version that has been published (not as a draft) by the Free Software Foundation. If the Document does not specify a version number of this License, you may choose any version ever published (not as a draft) by the Free Software Foundation. If the Document specifies that a proxy can decide which future versions of this License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Document. 11. RELICENSING "Massive Multiauthor Collaboration Site" (or "MMC Site") means any World Wide Web server that publishes copyrightable works and also provides prominent facilities for anybody to edit those works. A public wiki that anybody can edit is an example of such a server. A "Massive Multiauthor Collaboration" (or "MMC") contained in the site means any set of copyrightable works thus published on the MMC site. "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 license published by Creative Commons Corporation, a not-for-profit corporation with a principal place of business in San Francisco, California, as well as future copyleft versions of that license published by that same organization. "Incorporate" means to publish or republish a Document, in whole or in part, as part of another Document. An MMC is "eligible for relicensing" if it is licensed under this License, and if all works that were first published under this License somewhere other than this MMC, and subsequently incorporated in whole or in part into the MMC, (1) had no cover texts or invariant sections, and (2) were thus incorporated prior to November 1, 2008. The operator of an MMC Site may republish an MMC contained in the site under CC-BY-SA on the same site at any time before August 1, 2009, provided the MMC is eligible for relicensing. ADDENDUM: How to use this License for your documents ==================================================== To use this License in a document you have written, include a copy of the License in the document and put the following copyright and license notices just after the title page: Copyright (C) YEAR YOUR NAME. Permission is granted to copy, distribute and/or modify this document under the terms of the GNU Free Documentation License, Version 1.3 or any later version published by the Free Software Foundation; with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. A copy of the license is included in the section entitled ``GNU Free Documentation License''. If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the "with...Texts." line with this: with the Invariant Sections being LIST THEIR TITLES, with the Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. If you have Invariant Sections without Cover Texts, or some other combination of the three, merge those two alternatives to suit the situation. If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the GNU General Public License, to permit their use in free software.
