gnutls_x509_crt_get_preferred_hash_algorithm3
Api function
Usage
#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. |
Overview
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.
