NAME

6       gnutls_decode_ber_digest_info - API function
7

SYNOPSIS

9       #include <gnutls/crypto.h>
10
11       int    gnutls_decode_ber_digest_info(const   gnutls_datum_t   *   info,
12       gnutls_digest_algorithm_t * hash, unsigned char * digest, unsigned  int
13       * digest_size);
14

ARGUMENTS

16       const gnutls_datum_t * info
17                   an RSA BER encoded DigestInfo structure
18
19       gnutls_digest_algorithm_t * hash
20                   will contain the hash algorithm of the structure
21
22       unsigned char * digest
23                   will contain the hash output of the structure
24
25       unsigned int * digest_size
26                   will contain the hash size of the structure; initially must
27                   hold the maximum size of  digest
28

DESCRIPTION

30       This function will parse an RSA  PKCS1  1.5  DigestInfo  structure  and
31       report the hash algorithm used as well as the digest data.
32

RETURNS

34       On  success,  GNUTLS_E_SUCCESS (0) is returned, otherwise an error code
35       is returned.
