I use an OTR-plugin for Pidgin. It works fine with ICQ and Facebookchat and most likely with most other protocols too. x11-plugins/pidgin-otr There is even a compatible Plugin for Miranda (encrypted messages to Windows).

Kopete with the otr use flag supports Off The Record Encryption. This is THE method when communicating over a totally open channel like the internet. The message is encrypted on your computer and decrypted on the receivers computer. A drawback is that you have to handshake with each of the receivers first.

It's very interesting, however, I'm not a jabber user. But I'll check it again if any friend of mine is using jabber, since the GPG plugin is very attractive to me. Best regards, Wen TLS is widely-deployed on XMPP (jabber) servers, but encryption ends at the server in question, so it can intercept / mangle the messages, so it might be good idea to prefer large and reliable servers to possibly-compromised or malicious small ones. Furthermore, in case of XMPP, your (source) server is free to pass the message in unencrypted form to destination server, so message can be caught by any IP-sniffers on the route. Then there's also remote client connection, which can be unencrypted (no TLS/SSL) and likewise intercepted on TCP/IP level. GPG encryption requires clients on both sides to support it, but has benefit that all cryptographic operations are happening on client machines, so server (or any intermediate host) is unable to spoof conversation, provided the encryption (GPG) keys aren't compromised. -- Mike Kazantsev // fraggod.net -- Xianwen Chen Mobile: +86 13774 228909 Email: cxi...@post.uit.no; xianwen.c...@gmail.com
