.SH NAME
gnutls_privkey_sign_data \- API function
.SH SYNOPSIS
.B #include <gnutls/abstract.h>
.sp
.BI "int gnutls_privkey_sign_data(gnutls_privkey_t " signer ", gnutls_digest_algorithm_t " hash ", unsigned int " flags ", const gnutls_datum_t * " data ", gnutls_datum_t * " signature ");"
.SH ARGUMENTS
.IP "gnutls_privkey_t signer" 12
Holds the key
.IP "gnutls_digest_algorithm_t hash" 12
should be a digest algorithm
.IP "unsigned int flags" 12
Zero or one of \fBgnutls_privkey_flags_t\fP
.IP "const gnutls_datum_t * data" 12
holds the data to be signed
.IP "gnutls_datum_t * signature" 12
will contain the signature allocated with \fBgnutls_malloc()\fP
.SH "DESCRIPTION"
This function will sign the given data using a signature algorithm
supported by the private key. Signature algorithms are always used
together with a hash functions. Different hash functions may be
used for the RSA algorithm, but only the SHA family for the DSA keys.
You may use \fBgnutls_pubkey_get_preferred_hash_algorithm()\fP to determine
the hash algorithm.
.SH "RETURNS"
On success, \fBGNUTLS_E_SUCCESS\fP (0) is returned, otherwise a
negative error value.
.SH "SINCE"
2.12.0
.SH "REPORTING BUGS"
Report bugs to <bugs@gnutls.org>.
