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
