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.
