+
+        For client authentication, use one of these argument
+        combinations:
+         - username, password (SRP)
+         - username, sharedKey (shared-key)
+         - certChain, privateKey (certificate)
+
+        For server authentication, you can either rely on the
+        implicit mutual authentication performed by SRP or
+        shared-keys, or you can do certificate-based server
+        authentication with one of these argument combinations:
+         - cryptoID[, protocol] (requires cryptoIDlib)
+         - x509Fingerprint
+         - x509TrustList[, x509CommonName] (requires cryptlib_py)
+
+        Certificate-based server authentication is compatible with
+        SRP or certificate-based client authentication.  It is
+        not compatible with shared-keys.
+
+        The caller should be prepared to handle TLS-specific
+        exceptions.  See the client handshake functions in
+        L{tlslite.TLSConnection.TLSConnection} for details on which
+        exceptions might be raised.

+        one of these root certificates.  The cryptlib_py module must be
