gnutls_privkey_sign_hash - API function
#include <gnutls/abstract.h>
int gnutls_privkey_sign_hash(gnutls_privkey_t signer,
gnutls_digest_algorithm_t hash_algo, unsigned int flags, const
gnutls_datum_t * hash_data, gnutls_datum_t * signature);
gnutls_privkey_t signer
Holds the signer's key
gnutls_digest_algorithm_t hash_algo
The hash algorithm used
unsigned int flags
Zero or one of gnutls_privkey_flags_t
const gnutls_datum_t * hash_data
holds the data to be signed
gnutls_datum_t * signature
will contain newly allocated signature
This function will sign the given hashed 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-XXX for the DSA keys.
You may use gnutls_pubkey_get_preferred_hash_algorithm() to determine
the hash algorithm.
Note that if GNUTLS_PRIVKEY_SIGN_FLAG_TLS1_RSA flag is specified this
function will ignore hash_algo and perform a raw PKCS1 signature.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative
error value.
