I use encryption at work because my work will monitor everything transferred over the network to ensure that "confidential information isn't transmitted". I view this as an invasion of my privacy if I am chatting with a friend while on break. It would be great if there were an option with this plugin that would disable logging conversations to file when sending/receiving encrypted messages. All my transmissions are encrypted, but they are written to human readable plain text files on my work laptop.
Even better would be to encrypt the log file... but that may be asking too much.
