Package pyxmpp2 :: Package sasl :: Module scram :: Class SCRAM_SHA_1_PLUS_ServerAuthenticator

Class SCRAM_SHA_1_PLUS_ServerAuthenticator

The SCRAM-SHA-1-PLUS server authenticator.

Authentication properties used: same as for SCRAM_SHA_1_ServerAuthenticator, plus:

"channel-binding" - channel-binding data, as a dictionary channel-binding-type (unicode) -> channel-binding data(bytes). Channel binding type should be 'tls-unique', as other may be not supported by the other side.

Authentication properties returned: same as for SCRAM_SHA_1_ServerAuthenticator

Method Details

[hide private]

init(self, password_database)
(Constructor)

Initialize a SCRAMClientAuthenticator object.

Parameters:

hash_function_name - hash function name, e.g. "SHA-1"
channel_binding - True to enable channel binding

Overrides: object.__init__

(inherited documentation)

are_properties_sufficient(cls, properties)
Class Method

Check if the provided properties are sufficient for
this authentication mechanism.

If `are_properties_sufficient` returns False for given `properties`
mapping, the `start` method of `cls` instance will also fail with
such argument.

:Parameters:
    - `properties`: the `authentication properties`_
:Types:
    - `properties`: mapping

:Return: if the mechanism can be used with those properties

Overrides: core.ServerAuthenticator.are_properties_sufficient: (inherited documentation)
