I want to add OTR (Off the record) Messaging into my (XMPP) chat application, which is written in java. A quick google search showed at least two possible libraries:
- java-otr: http://www.cypherpunks.ca/otr/index.php#downloads
that is the one gibberbot uses, last change Oct 2009 - otr4j: http://code.google.com/p/otr4j/ – last change Aug 2010
Short question: Which one should I choose?
Long question: The library should of course provide a decent level of interoperability, so that the OTR messaging works with the various XMPP client that are out there. Also some pros/cons of the library you suggest would be nice. Basically everything that could be interesting for me. 🙂
Besides the original from cypherpunks which seemed to be the way to go a few years ago, there is also a maintained version at https://github.com/otr4j/otr4j (See Hans-Christoph Steiner’s comment).
