int gnutls_pubkey_get_preferred_hash_algorithm(gnutls_pubkey_t key,
gnutls_digest_algorithm_t * hash, unsigned int * mand);
Holds the certificate

The result of the call with the hash algorithm used for
unsigned int * mand
If non zero it means that the algorithm MUST use this hash.
May be NULL.
This function will read the certifcate and return the appropriate
digest algorithm to use for signing with this certificate. Some cer‐
tificates (i.e. DSA might not be able to sign without the preferred
To get the signature algorithm instead of just the hash use
