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. New keys are generated on the fly (off the
record) such that if your secret key is compromised no old messages can
be decrypted still. Wikipedia has a small article about it and it works
quite easily once set up in kopete.

The fundamental theorem of algebra is open source. Like any other
mathematical theorem it can be applied free of charge and everybody
has access to its proof and can convince himself how it works. Why
should software be any different?
