I think you're missing the point of the contest. This is not about cryptography. The key generation is just an excuse. The fact that you can detect a connection with DevTools is irrelevant. The idea is too write code that is clean, readable, and innocent looking, but does something "malicious". It's just about having fun obfuscating code, not to write the next exploit.
