"""Create a new XMLRPCTransport.
|
|
|
|
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.

'password' or 'sharedKey' argument.

|
|
@param password: SRP password for mutual authentication.
|
|
Requires the 'username' argument.

@param sharedKey: Shared key for mutual authentication.

L{cryptoIDlib.CertChain.CertChain}

|
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.

@param settings: Various settings which can be used to control

the ciphersuites, certificate types, and SSL/TLS versions

offered by the client.
