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 * 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.
