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 re-
       port 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
