E2EEPlugin
|
|
----------
|
|
|
|
.. module:: poezio.plugin_e2ee
|
|
|
|
|
|
.. autoclass:: E2EEPlugin
|
|
:members:
|
|
|
|
Builds on top of :py:class:`~BasePlugin` and requires the developer to
|
|
implement two methods, `decrypt` and `encrypt`, as well as the
|
|
`encryption_name` and `eme_ns` attribute.
|
|
|
|
Please refer to :py:class:`~BasePlugin` for more information on how to
|
|
write plugins.
