NAME

gnutls_decode_ber_digest_info - API function

SYNOPSIS

#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

DESCRIPTION

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.

SINCE

3.5.0
