gnutls_fingerprint — calculate the fingerprint of the given data
#include <gnutls/gnutls.h>
int
gnutls_fingerprint( |
gnutls_digest_algorithm_t | algo, |
| const gnutls_datum_t * | data, | |
| void * | result, | |
| size_t * | result_size); |
is a digest algorithm
is the data
is the place where the result will be copied (may be null).
should hold the size of the result. The actual size of the returned result will also be copied there.
This function will calculate a fingerprint (actually a hash), of the given data. The result is not printable data. You should convert it to hex, or to something else printable.
This is the usual way to calculate a fingerprint of an X.509 DER encoded certificate. Note however that the fingerprint of an OpenPGP is not just a hash and cannot be calculated with this function.
The full documentation for gnutls is maintained as a Texinfo manual. If the info and gnutls programs are properly installed at your site, the command
info gnutls
should give you access to the complete manual.
