gnutls_x509_crt_get_fingerprint3
Api function
Usage
#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_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 |
Overview
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.
