NAME

6       gnutls_x509_crt_get_preferred_hash_algorithm - API function
7

SYNOPSIS

9       #include <gnutls/x509.h>
10
11       int gnutls_x509_crt_get_preferred_hash_algorithm(gnutls_x509_crt_t crt,
12       gnutls_digest_algorithm_t                                             *
13       hash, unsigned int * mand);
14

ARGUMENTS

16       gnutls_x509_crt_t crt
17                   Holds the certificate
18
19       gnutls_digest_algorithm_t                                             *
20       hash
21                   The result of the call with the  hash  algorithm  used  for
22                   signature
23
24       unsigned int * mand
25                   If non zero it means that the algorithm MUST use this hash.
26                   May be NULL.
27

DESCRIPTION

29       This function will read  the  certifcate  and  return  the  appropriate
30       digest  algorithm  to  use for signing with this certificate. Some cer‐
31       tificates (i.e.  DSA might not be able to sign  without  the  preferred
32       algorithm).
33

DEPRECATED

35       Please use gnutls_pubkey_get_preferred_hash_algorithm().
36

RETURNS

38       the  0  if the hash algorithm is found. A negative value is returned on
39       error.
