NAME

6       gnutls_x509_crt_get_fingerprint - API function
7

SYNOPSIS

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

ARGUMENTS

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

DESCRIPTION

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

RETURNS

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