NAME
gnutls_x509_privkey_sign_data - sign data using the private keySYNOPSIS
#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);
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.
RETURNS
On success, GNUTLS_E_SUCCESS is returned, otherwise a negative error value.REPORTING BUGS
