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_di-
     gest_algorithm_t * hash,  unsigned  char  *  digest,  unsigned  int  *  di-
     gest_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
