+
+        An instance of this class can be passed to L{xmlrpclib.ServerProxy}
+        to use TLS with XML-RPC calls::
+
+            from tlslite.api import XMLRPCTransport
+            from xmlrpclib import ServerProxy
+
+            transport = XMLRPCTransport(user="alice", password="abra123")
+            server = ServerProxy("https://localhost", transport)
+
+        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 constructor does not perform the TLS handshake itself, but
+        simply stores these arguments for later.  The handshake is
+        performed only when this class needs to connect with the
+        server.  Thus you should be prepared to handle TLS-specific
+        exceptions when calling methods of L{xmlrpclib.ServerProxy}.  See the
+        client handshake functions in
+        L{tlslite.TLSConnection.TLSConnection} for details on which
+        exceptions might be raised.

+        Requires the 'privateKey' argument.  Excludes the SRP or
+        shared-key related arguments.
+
+        @type privateKey: L{tlslite.utils.RSAKey.RSAKey}
+        @param privateKey: Private key for client authentication.
+        Requires the 'certChain' argument.  Excludes the SRP or
+        shared-key related arguments.
+
+        @type cryptoID: str
+        @param cryptoID: cryptoID for server authentication.  Mutually
+        exclusive with the 'x509...' arguments.
+
+        @type protocol: str
+        @param protocol: cryptoID protocol URI for server
+        authentication.  Requires the 'cryptoID' argument.
+
+        @type x509Fingerprint: str
+        @param x509Fingerprint: Hex-encoded X.509 fingerprint for
+        server authentication.  Mutually exclusive with the 'cryptoID'
+        and 'x509TrustList' arguments.
+
+        @type x509TrustList: list of L{tlslite.X509.X509}
+        @param x509TrustList: A list of trusted root certificates.  The
+        other party must present a certificate chain which extends to
+        one of these root certificates.  The cryptlib_py module must be
+        installed to use this parameter.  Mutually exclusive with the
+        'cryptoID' and 'x509Fingerprint' arguments.
+
+        @type x509CommonName: str
+        @param x509CommonName: The end-entity certificate's 'CN' field
+        must match this value.  For a web server, this is typically a
+        server name such as 'www.amazon.com'.  Mutually exclusive with
+        the 'cryptoID' and 'x509Fingerprint' arguments.  Requires the
+        'x509TrustList' argument.

+        offered by the client.
