gnutls_x509_privkey_sign_data( |
gnutls_x509_privkey_t | key, |
| gnutls_digest_algorithm_t | digest, | |
| unsigned int | flags, | |
| const gnutls_datum_t * | data, | |
| void * | signature, | |
| size_t * | signature_size); |
Holds the key
should be MD5 or SHA1
should be 0 for now
holds the data to be signed
will contain the signature
holds the size of signature (and will be replaced by the new size)
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 SHA−1 for the DSA keys.
If the buffer provided is not long enough to hold the output, then *signature_size is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be returned.
In case of failure a negative value will be returned, and 0 on success.
The full documentation for gnutls is maintained as a Texinfo manual. If the info and gnutls programs are properly installed at your site, the command
info gnutls
should give you access to the complete manual.
