It can handle +both unencrypted PKCS#8 PrivateKeyInfo format and EncryptedPrivateKeyInfo +format with a variety of PKCS#5 (v1.5 and v2.0) and PKCS#12 algorithms. +.SH OPTIONS +.IX Header "OPTIONS" +.IP \fB\-help\fR 4 +.IX Item "-help" +Print out a usage message. +.IP \fB\-topk8\fR 4 +.IX Item "-topk8" +Normally a PKCS#8 private key is expected on input and a private key will be +written to the output file. With the \fB\-topk8\fR option the situation is +reversed: it reads a private key and writes a PKCS#8 format key. +.IP "\fB\-inform\fR \fBDER\fR|\fBPEM\fR, \fB\-outform\fR \fBDER\fR|\fBPEM\fR" 4 +.IX Item "-inform DER|PEM, -outform DER|PEM" +The input and formats; the default is \fBPEM\fR. +See \fBopenssl\-format\-options\fR\|(1) for details. +.Sp +If a key is being converted from PKCS#8 form (i.e. the \fB\-topk8\fR option is +not used) then the input file must be in PKCS#8 format. An encrypted +key is expected unless \fB\-nocrypt\fR is included. +.Sp +If \fB\-topk8\fR is not used and \fBPEM\fR mode is set the output file will be an +unencrypted private key in PKCS#8 format. If the \fB\-traditional\fR option is +used then a traditional format private key is written instead. +.Sp +If \fB\-topk8\fR is not used and \fBDER\fR mode is set the output file will be an +unencrypted private key in traditional DER format. +.Sp +If \fB\-topk8\fR is used then any supported private key can be used for the input +file in a format specified by \fB\-inform\fR. The output file will be encrypted +PKCS#8 format using the specified encryption parameters unless \fB\-nocrypt\fR +is included. +.IP \fB\-traditional\fR 4 +.IX Item "-traditional" +When this option is present and \fB\-topk8\fR is not a traditional format private +key is written. +.IP "\fB\-in\fR \fIfilename\fR" 4 +.IX Item "-in filename" +This specifies the input filename to read a key from or standard input if this +option is not specified. If the key is encrypted a pass phrase will be +prompted for. +.IP "\fB\-passin\fR \fIarg\fR, \fB\-passout\fR \fIarg\fR" 4 +.IX Item "-passin arg, -passout arg" +The password source for the input and output file. +For more information about the format of \fBarg\fR +see \fBopenssl\-passphrase\-options\fR\|(1). +.IP "\fB\-out\fR \fIfilename\fR" 4 +.IX Item "-out filename" +This specifies the output filename to write a key to or standard output by +default. If any encryption options are set then a pass phrase will be +prompted for. The output filename should \fBnot\fR be the same as the input +filename. +.IP "\fB\-iter\fR \fIcount\fR" 4 +.IX Item "-iter count" +When creating new PKCS#8 containers, use a given number of iterations on +the password in deriving the encryption key for the PKCS#8 output. +High values increase the time required to brute-force a PKCS#8 container. +.IP \fB\-noiter\fR 4 +.IX Item "-noiter" +When creating new PKCS#8 containers, use 1 as iteration count. +.IP \fB\-nocrypt\fR 4 +.IX Item "-nocrypt" +PKCS#8 keys generated or input are normally PKCS#8 EncryptedPrivateKeyInfo +structures using an appropriate password based encryption algorithm. With +this option an unencrypted PrivateKeyInfo structure is expected or output. +This option does not encrypt private keys at all and should only be used +when absolutely necessary. Certain software such as some versions of Java +code signing software used unencrypted private keys. +.IP "\fB\-v2\fR \fIalg\fR" 4 +.IX Item "-v2 alg" +This option sets the PKCS#5 v2.0 algorithm. +.Sp +The \fIalg\fR argument is the encryption algorithm to use, valid values include +\&\fBaes128\fR, \fBaes256\fR and \fBdes3\fR. If this option isn't specified then \fBaes256\fR +is used. +.IP "\fB\-v2prf\fR \fIalg\fR" 4 +.IX Item "-v2prf alg" +This option sets the PRF algorithm to use with PKCS#5 v2.0. A typical value +value would be \fBhmacWithSHA256\fR. If this option isn't set then the default +for the cipher is used or \fBhmacWithSHA256\fR if there is no default. +.Sp +Some implementations may not support custom PRF algorithms and may require +the \fBhmacWithSHA1\fR option to work. +.IP "\fB\-v1\fR \fIalg\fR" 4 +.IX Item "-v1 alg" +This option indicates a PKCS#5 v1.5 or PKCS#12 algorithm should be used. Some +older implementations may not support PKCS#5 v2.0 and may require this option. +If not specified PKCS#5 v2.0 form is used. +.IP \fB\-scrypt\fR 4 +.IX Item "-scrypt" +Uses the \fBscrypt\fR algorithm for private key encryption using default +parameters: currently N=16384, r=8 and p=1 and AES in CBC mode with a 256 bit +key. These parameters can be modified using the \fB\-scrypt_N\fR, \fB\-scrypt_r\fR, +\&\fB\-scrypt_p\fR and \fB\-v2\fR options. +.IP "\fB\-scrypt_N\fR \fIN\fR, \fB\-scrypt_r\fR \fIr\fR, \fB\-scrypt_p\fR \fIp\fR" 4 +.IX Item "-scrypt_N N, -scrypt_r r, -scrypt_p p" +Sets the scrypt \fIN\fR, \fIr\fR or \fIp\fR parameters. +.IP \fB\-saltlen\fR 4 +.IX Item "-saltlen" +Sets the length (in bytes) of the salt to use for the PBE algorithm. +If this value is not specified, the default for PBES2 is 16 (128 bits) +and 8 (64 bits) for PBES1. +.IP "\fB\-rand\fR \fIfiles\fR, \fB\-writerand\fR \fIfile\fR" 4 +.IX Item "-rand files, -writerand file" +See "Random State Options" in \fBopenssl\fR\|(1) for details. +.IP "\fB\-engine\fR \fIid\fR" 4 +.IX Item "-engine id" +See "Engine Options" in \fBopenssl\fR\|(1). +This option is deprecated. +.IP "\fB\-provider\fR \fIname\fR" 4 +.IX Item "-provider name" +.PD 0 +.IP "\fB\-provider\-path\fR \fIpath\fR" 4 +.IX Item "-provider-path path" +.IP "\fB\-propquery\fR \fIpropq\fR" 4 +.IX Item "-propquery propq" +.PD +See "Provider Options" in \fBopenssl\fR\|(1), \fBprovider\fR\|(7), and \fBproperty\fR\|(7). +.SH NOTES +.IX Header "NOTES" +By default, when converting a key to PKCS#8 format, PKCS#5 v2.0 using 256 bit +AES with HMAC and SHA256 is used. +.PP +Some older implementations do not support PKCS#5 v2.0 format and require +the older PKCS#5 v1.5 form instead, possibly also requiring insecure weak +encryption algorithms such as 56 bit DES. +.PP +Private keys encrypted using PKCS#5 v2.0 algorithms and high iteration +counts are more secure that those encrypted using the traditional +SSLeay compatible formats. So if additional security is considered +important the keys should be converted. +.PP +It is possible to write out DER encoded encrypted private keys in +PKCS#8 format because the encryption details are included at an ASN1 +level whereas the traditional format includes them at a PEM level. +.SH "PKCS#5 V1.5 AND PKCS#12 ALGORITHMS" +.IX Header "PKCS#5 V1.5 AND PKCS#12 ALGORITHMS" +Various algorithms can be used with the \fB\-v1\fR command line option, +including PKCS#5 v1.5 and PKCS#12. These are described in more detail +below. +.IP "\fBPBE\-MD2\-DES PBE\-MD5\-DES\fR" 4 +.IX Item "PBE-MD2-DES PBE-MD5-DES" +These algorithms were included in the original PKCS#5 v1.5 specification. +They only offer 56 bits of protection since they both use DES. +.IP "\fBPBE\-SHA1\-RC2\-64\fR, \fBPBE\-MD2\-RC2\-64\fR, \fBPBE\-MD5\-RC2\-64\fR, \fBPBE\-SHA1\-DES\fR" 4 +.IX Item "PBE-SHA1-RC2-64, PBE-MD2-RC2-64, PBE-MD5-RC2-64, PBE-SHA1-DES" +These algorithms are not mentioned in the original PKCS#5 v1.5 specification +but they use the same key derivation algorithm and are supported by some +software. They are mentioned in PKCS#5 v2.0. They use either 64 bit RC2 or +56 bit DES. +.IP "\fBPBE\-SHA1\-RC4\-128\fR, \fBPBE\-SHA1\-RC4\-40\fR, \fBPBE\-SHA1\-3DES\fR, \fBPBE\-SHA1\-2DES\fR, \fBPBE\-SHA1\-RC2\-128\fR, \fBPBE\-SHA1\-RC2\-40\fR" 4 +.IX Item "PBE-SHA1-RC4-128, PBE-SHA1-RC4-40, PBE-SHA1-3DES, PBE-SHA1-2DES, PBE-SHA1-RC2-128, PBE-SHA1-RC2-40" +These algorithms use the PKCS#12 password based encryption algorithm and +allow strong encryption algorithms like triple DES or 128 bit RC2 to be used. +.SH EXAMPLES +.IX Header "EXAMPLES" +Convert a private key to PKCS#8 format using default parameters (AES with +256 bit key and \fBhmacWithSHA256\fR): +.PP +.Vb 1 +\& openssl pkcs8 \-in key.pem \-topk8 \-out enckey.pem +.Ve +.PP +Convert a private key to PKCS#8 unencrypted format: +.PP +.Vb 1 +\& openssl pkcs8 \-in key.pem \-topk8 \-nocrypt \-out enckey.pem +.Ve +.PP +Convert a private key to PKCS#5 v2.0 format using triple DES: +.PP +.Vb 1 +\& openssl pkcs8 \-in key.pem \-topk8 \-v2 des3 \-out enckey.pem +.Ve +.PP +Convert a private key to PKCS#5 v2.0 format using AES with 256 bits in CBC +mode and \fBhmacWithSHA512\fR PRF: +.PP +.Vb 1 +\& openssl pkcs8 \-in key.pem \-topk8 \-v2 aes\-256\-cbc \-v2prf hmacWithSHA512 \-out enckey.pem +.Ve +.PP +Convert a private key to PKCS#8 using a PKCS#5 1.5 compatible algorithm +(DES): +.PP +.Vb 1 +\& openssl pkcs8 \-in key.pem \-topk8 \-v1 PBE\-MD5\-DES \-out enckey.pem +.Ve +.PP +Convert a private key to PKCS#8 using a PKCS#12 compatible algorithm +(3DES): +.PP +.Vb 1 +\& openssl pkcs8 \-in key.pem \-topk8 \-out enckey.pem \-v1 PBE\-SHA1\-3DES +.Ve +.PP +Read a DER unencrypted PKCS#8 format private key: +.PP +.Vb 1 +\& openssl pkcs8 \-inform DER \-nocrypt \-in key.der \-out key.pem +.Ve +.PP +Convert a private key from any PKCS#8 encrypted format to traditional format: +.PP +.Vb 1 +\& openssl pkcs8 \-in pk8.pem \-traditional \-out key.pem +.Ve +.PP +Convert a private key to PKCS#8 format, encrypting with AES\-256 and with +one million iterations of the password: +.PP +.Vb 1 +\& openssl pkcs8 \-in key.pem \-topk8 \-v2 aes\-256\-cbc \-iter 1000000 \-out pk8.pem +.Ve +.SH STANDARDS +.IX Header "STANDARDS" +Test vectors from this PKCS#5 v2.0 implementation were posted to the +pkcs-tng mailing list using triple DES, DES and RC2 with high iteration +counts, several people confirmed that they could decrypt the private +keys produced and therefore, it can be assumed that the PKCS#5 v2.0 +implementation is reasonably accurate at least as far as these +algorithms are concerned. +.PP +The format of PKCS#8 DSA (and other) private keys is not well documented: +it is hidden away in PKCS#11 v2.01, section 11.9.
