Jan van Swinden was one of his most important students.

gollark: It uses just one 4-byte key which it XORs with everything and yet people weren't able to trivially reverse it?
gollark: It's reading a key from memory somewhere, doesn't mean it uses the *same* key for everything.
gollark: No sensible cryptographic algorithm would XOR all the data with exactly the same thing, because that would, as you demonstrated, be hilariously insecure.
gollark: Sure. But it would be easy to make it not do that. I could do that, even.
gollark: Oh, you mean the malware is really stupid and uses a hardcoded key?
