gnutls_x509_...t_fingerprint(3) gnutls gnutls_x509_...t_fingerprint(3)
gnutls_x509_crt_get_fingerprint - API function
#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);
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
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.
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.
