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().
