A reverse engineer, a web hacker, and a cryptographer walk into a bar.

The web hacker orders a beer and tries to hand the bartender: admin' OR 1=1 --.

The reverse engineer starts taking the tap apart piece by piece just to figure out how the beer flows.

Meanwhile, the cryptographer sits in the corner, stares at the receipt, and says:
— "Guys, I have no idea how much this costs, but I can tell you one thing for sure: the total ends in ==, so it's definitely Base64!"
