COUGH IPQ
yes hello
zsno is right, the first five characters are just your BLID encoded in a special way, specifically base 32 with the characters "ABCDEFGHJKLMNPQRSTUVWXYZ23456
789" where A is 0 B is 1, etc... If you don't understand that, no problem, just know it isn't dangerous if someone finds out the first 5 characters of your key. mine is AAKCM, go wild
edit: you literally said you found out from my program lol nevermind
