GEVR

This addon is an early (though hopefully working) implementation of reasonably secure communication over the WoW UI. It has no purpose beyond toying with the concept of securely agreeing on a secret key and using it to trade messages that only log as unreadable data.

Diffie-Hellman key exchange is used to generate a session key, and this in turn is used to generate a keystream to encode each character.

Usage:

• Begin by opening the addon's main window with the slash-command /gevr.
• Enter the name of another player and click Add. If they also have the addon, each of you will appear in each other's contact list.
• Click Key to begin key generation.*
• When both of you have completed that, click Hash to complete the final key.*
• Click Msg (or use /tx <name> <message>) to send a secure message.
• Use /kreset <name> if you need to start over.

*These two procedures need a lot of computing time, and I have built in a slider to help with throttling the number of operations per frame. A lower setting will take longer to make a key, but leave your game FPS almost untouched. A higher setting will hit your game FPS while making a key, but the key will be ready sooner. This process never triggers automatically, only when you choose it to.

Apologies for the relative clunkiness and lack of a few obvious features; this is my first actual add-on beyond personal tweaks to the UI, so still picking things up as I go
