◦ I'm just looking for anything that manipulates the data on a low level. e.g. replacing /me with asterisks and the username, or emoticons, etc.
◦ The task is in doing it at all; not in the scope of what it accomplishes

◦ Person A writes something; Persons B and C see that something
▪ i.e. a chat room

◦ This doesn't imply authentication or accounts or anything like that; just choose a name once, and always prepend it to chats

◦ Person A writes something; Person B sees that something; an eavesdropper mid-stream wouldn't understand it
◦ Feel free to simply connect openssl
◦ 'Strength' of encryption isn't a factor. It's fine to hardcode passwords/keys, if used
◦ It's acceptable to do trivial transformations
▪ e.g. simplying XOR'ing every byte, or running text through base64 encoding
▪ The only requirement is to make it unreadable at a casual glance

◦ Person A writes something; Person B sees that something
◦ At the socket level, you may wish to encapsulate this, or prepend some small bit of text (to distinguish it from file transfers or commands, below)
◦ Either party may send multiple messages, and may quit
▪ It's up to you how you expect them to 'quit'
