Help with creating a plugin (my master thesis)

[Randolph]

Hi Agnieszka
good idea with the plugin for encryption, but why such a complicated
process? Encryption on XMPP just needs to swap one key for one time. Look
how other clients have done it: goo.gl/kH9dcK  could be a reference model
for your work.
