NAME
gnutls_pubkey_get_preferred_hash_algorithm - API function
SYNOPSIS
#include <gnutls/abstract.h>
int gnutls_pubkey_get_preferred_hash_algorithm(gnutls_pubkey_t */key/, gnutls_digest_algorithm_t * hash, unsigned int * mand);*
ARGUMENTS
- gnutls_pubkey_t key
- Holds the certificate
- gnutls_digest_algorithm_t * hash
- The result of the call with the hash algorithm used for signature
- unsigned int * mand
- If non zero it means that the algorithm MUST use this hash. May be NULL.
DESCRIPTION
This function will read the certificate and return the appropriate digest algorithm to use for signing with this certificate. Some certificates (i.e. DSA might not be able to sign without the preferred algorithm).
To get the signature algorithm instead of just the hash use gnutls_pk_to_sign() with the algorithm of the certificate/key and the provided hash .
RETURNS
the 0 if the hash algorithm is found. A negative error code is returned on error.

2.12.0
