gnutls_x509_crt_get_fingerprint(3)  gnutls  gnutls_x509_crt_get_fingerprint(3)

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.
