OTR support for emacs-jabber; work in progress. How to use it: 1. Install python-potr. Run: sudo pip install python-potr or see https://github.com/python-otr/pure-python-otr . 2. Load jabber-otr.el. 3. Open a chat buffer (either by an incoming message, or by C-x C-j C-j). 4a. If the other contact activates OTR, the chat buffer should switch to encrypted mode automatically. 4b. To request OTR, type M-x jabber-otr-encrypt. 5. Send and receive messages as usual, more or less. TODO: verify signatures, improve UI, handle HTML.
