gnutls_decode_ber_digest_info - Man Page

#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);

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

This function will parse an RSA PKCS1 1.5 DigestInfo structure and report the hash algorithm used as well as the digest data.

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error code is returned.
