NAME
gnutls_x509_crt_get_fingerprint - This function returns the
Certificate’s fingerprint
SYNOPSIS
#include <gnutls/x509.h>
int gnutls_x509_crt_get_fingerprint(gnutls_x509_crt_t cert,
gnutls_digest_algorithm_t algo, void * buf, size_t * sizeof_buf);
ARGUMENTS
gnutls_x509_crt_t cert
should contain a gnutls_x509_crt_t structure
gnutls_digest_algorithm_t algo
is a digest algorithm
void * buf a pointer to a structure to hold the fingerprint (may be
null)
size_t * sizeof_buf
initially holds the size of buf
DESCRIPTION
This function will calculate and copy the certificate’s fingerprint in
the provided buffer.
If the buffer is null then only the size will be filled.
RETURNS
GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long enough,
and in that case the *sizeof_buf will be updated with the required
size. On success 0 is returned.
