I'm a little confused by this. How can it be a group chat with end to end encryption? Surely everyone logged into the chat room would need to read the messages, so it's really no more secure than IRC over SSL. Or is this actually more like a peer-to-peer instant messenger?

I haven't looked at the code itself, but based on the usage section it seems like everyone in the room shares a secret key. I think the concept is that in order to get the secret key, you have to explicitly be given it by someone in the room.

By the way, there's an already-existing secure group chat software, SILC, that does something similar: https://en.wikipedia.org/wiki/SILC_%28protocol%29 (see "security" section, and technical details in http://www.silcnet.org/support/faq/crypto/ )
