Do not use this function directly unless you know what it is. Typical signing requires the data to be hashed and stored in special formats (e.g. BER Digest\-Info for RSA). This API is provided only for backwards compatibility, and thus restricted to RSA, DSA and ECDSA key types. For other key types please use \fBgnutls_privkey_sign_hash()\fP and \fBgnutls_privkey_sign_data()\fP. .SH "RETURNS" On success, \fBGNUTLS_E_SUCCESS\fP (0) is returned, otherwise a negative error value.
