gnutls_decode_ber_digest_info3
Api function
Usage
#include <gnutls/crypto.h>
int gnutls_decode_ber_digest_info(const gnutls_datum_t * info, gnutls_digest_algorithm_t * hash, unsigned char * digest, unsigned int * digest_size);
Arguments
- const gnutls_datum_t * info
-
an RSA BER encoded DigestInfo structure
- gnutls_digest_algorithm_t * hash
-
will contain the hash algorithm of the structure
- unsigned char * digest
-
will contain the hash output of the structure
- unsigned int * digest_size
-
will contain the hash size of the structure; initially must hold the maximum size of digest
Overview
This function will parse an RSA PKCS1 1.5 DigestInfo structure and report the hash algorithm used as well as the digest data.
Returns
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error code is returned.
