SecureIM
From Wikipedia, the free encyclopedia
SecureIM is an encryption system built into the Trillian Instant Messenger Client.
It encrypts messages from user-to-user, so no passively observing node between the two is supposedly able to read the encrypted messages. SecureIM does not authenticate its messages, and therefore it is susceptible to active attacks including simple forms of man in the middle.
According to Cerulean Studios, the makers of Trillian, SecureIM enciphers messages with 128-bit Blowfish encryption. It only works with the OSCAR protocol and if both chat partners use Trillian.
