Intego ChatBarrier X3
, a program that works in conjunction with Apple's iChat instant messaging software to provide two-way, real-time encryption of text chats using 512-bit encryption. "Apple’s iChat instant messaging is not a peer-to-peer technology. Text messages are sent in clear text, and go through the AIM server, as well as through dozens of others before finally being routed to the intended correspondent. No one knows how secure or reliable any of these servers are." ChatBarrier X3 ($40 for two licenses) uses a stream cipher to encrypt messages as soon as they are sent. It runs on Mac OS X 10.1.1 or later. [pricing, product link added]
