NAME

gnutls_x509_crt_get_preferred_hash_algorithm - API function

SYNOPSIS

#include <gnutls/compat.h>

int gnutls_x509_crt_get_preferred_hash_algorithm(gnutls_x509_crt_t crt, gnutls_digest_algorithm_t * hash, unsigned int * mand);

ARGUMENTS

gnutls_x509_crt_t crt: 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).

DEPRECATED

Please use gnutls_pubkey_get_preferred_hash_algorithm().

RETURNS

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

SINCE

2.12.0
