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.
