NAME

6       gnutls_x509_crt_get_fingerprint  -  This  function returns the Certifi‐
7       cate's fingerprint
8

SYNOPSIS

10       #include <gnutls/x509.h>
11
12       int       gnutls_x509_crt_get_fingerprint(gnutls_x509_crt_t       cert,
13       gnutls_digest_algorithm_t algo, void * buf, size_t * sizeof_buf);
14

ARGUMENTS

16       gnutls_x509_crt_t cert
17                   should contain a gnutls_x509_crt_t structure
18
19       gnutls_digest_algorithm_t algo
20                   is a digest algorithm
21
22       void * buf  a  pointer  to  a structure to hold the fingerprint (may be
23                   null)
24
25       size_t * sizeof_buf
26                   initially holds the size of buf
27

DESCRIPTION

29       This function will calculate and copy the certificate's fingerprint  in
30       the provided buffer.
31
32       If the buffer is null then only the size will be filled.
33

RETURNS

35       GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long enough,
36       and in that case the *sizeof_buf will  be  updated  with  the  required
37       size.  On success 0 is returned.
