NAME
gnutls_x509_crt_get_fingerprint - API function
SYNOPSIS
#include <gnutls/x509.h>
int gnutls_x509_crt_get_fingerprint(gnutls_x509_crt_t cert, gnutls_di-
gest_algorithm_t algo, void * buf, size_t * buf_size);
ARGUMENTS
gnutls_x509_crt_t cert
should contain a gnutls_x509_crt_t type
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 * buf_size
initially holds the size of buf
DESCRIPTION
This function will calculate and copy the certificate's fingerprint in
the provided buffer. The fingerprint is a hash of the DER-encoded data
of the certificate.
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 *buf_size will be updated with the required size.
On success 0 is returned.
