NAME         top

       gnutls_x509_crt_get_fingerprint - API function

SYNOPSIS         top

       #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         top

       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         top

       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         top

       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.
