Encrypt your chat messages so nobody else can see them!

Features:

• Encrypt any message, or part of a message, by surrounding it with enc:;
• Works on Vanilla servers
• Easily configurable encryption key under 'Mod Options'
• Current encryption key is displayed in the HUD while playing
• Keyboard shortcut to skip all the work of typing 5 letters to mark a chat message to be encrypted, default is '>'

Admins have this thing called socialspy where they can monitor everything you're sending via the supposedly private /msg command, so now you can do this when you use that command:

/msg MyFriend enc:secret message here;

I'm going to update this to 1.13 soon guys don't worry. I just remembered I even made this in the first place lol. The next version will also improve the way encrypted messages are encoded so they can be way longer. What was I thinking with the 2f|5e|d7|etc|etc thing?

It's available for 1.12.2 now. Forge 1.13 isn't available yet sorry, but I can still make a 1.13 compatible version using regular vanilla tweakers if anyone's interested. This shouldn't really matter though because most servers still support the older versions of minecraft anyway.
