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
DESCRIPTIONThis 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.
RETURNSGNUTLS_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.
