Salt/Tripcodes and Whitelist Basics
Salt/Tripcodes
Think of Salt as a Tripcode (TC) generation engine.
You supply it a password and it outputs a unique string.
If the engine changes (rotation) then a different string will get generated by your password.
That string is what displays when you post using a TC.
Whitelist
This is just a listing of TCs that you allow to post on your board.
If your string is in there you're good to go.
If not then you can't post using a TC there.
