NAME

6       gnutls_pubkey_get_preferred_hash_algorithm - API function
7

SYNOPSIS

9       #include <gnutls/abstract.h>
10
11       int   gnutls_pubkey_get_preferred_hash_algorithm(gnutls_pubkey_t   key,
12       gnutls_digest_algorithm_t *         hash, unsigned int * mand);
13

ARGUMENTS

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

DESCRIPTION

27       This function will read the certificate and return the appropriate  di‐
28       gest  algorithm to use for signing with this certificate. Some certifi‐
29       cates (i.e.  DSA might not be able to sign without the preferred  algo‐
30       rithm).
31
32       To   get   the  signature  algorithm  instead  of  just  the  hash  use
33       gnutls_pk_to_sign() with the algorithm of the certificate/key  and  the
34       provided  hash .
35

RETURNS

37       the 0 if the hash algorithm is found. A negative error code is returned
38       on error.
