gnutls_x509_privkey_sign_data(3) gnutls gnutls_x509_privkey_sign_data(3)
gnutls_x509_privkey_sign_data - API function
#include <gnutls/x509.h>
int 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);
gnutls_x509_privkey_t key
a key
gnutls_digest_algorithm_t digest
should be a digest algorithm
unsigned int flags
should be 0 for now
const gnutls_datum_t * data
holds the data to be signed
void * signature
will contain the signature
size_t * signature_size
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.
Use gnutls_x509_crt_get_preferred_hash_algorithm() to determine
the hash algorithm.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a
negative error value.
