by Shatterbox Reverse Engineering Some dude's been trying to hide even more secrets behind yet another one of his "all-new, totally one-of-a-kind encryption algorithms" that he'd been yapping about.

Apparently it's some sort of "subleq emulator" that runs thousands of iterations of an image encryption algorithm... before straight-up memdumping the entire program state into a binary file when it's done.

All of it.

Given that he was kind enough to send us an encrypted file, that probably means the algorithm's open-source now.

Nobody tell him.
