NAME

gnutls_x509_privkey_sign_data - API function  

SYNOPSIS

#include <gnutls/compat.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);  

ARGUMENTS

gnutls_x509_privkey_t key
Holds the key
gnutls_digest_algorithm_t digest
should be MD5 or SHA1
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)
 

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 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.  

RETURNS

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.  

DEPRECATED

Use gnutls_privkey_sign_data().
