/**
 * gnutls_x509_crt_sign:
 * @crt: a certificate of type #gnutls_x509_crt_t
 * @issuer: is the certificate of the certificate issuer
 * @issuer_key: holds the issuer's private key
 *
 * This function is the same a gnutls_x509_crt_sign2() with no flags,
 * and SHA1 as the hash algorithm.
 *
 * Returns: On success, %GNUTLS_E_SUCCESS (0) is returned, otherwise a
