gnutls_x509_crt_t | cert, |

should contain a gnutls_x509_crt_t structure
is a digest algorithm
a pointer to a structure to hold the fingerprint (may be null)
initially holds the size of buf
This function will calculate and copy the certificate's fingerprint in the provided buffer.
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 *sizeof_buf will be updated with the required size. On success 0 is returned.
