I am really failing to understand the distinction here. Encryption with say, AES has very different properties and use cases compared to an obfuscation scheme. You can use encryption as a part of an obfuscation scheme, but obfuscation is a shell game, all the way down. Crypto is not, mathematically. They are categorically different things, right?
- grog454 4y agoThe math is irrelevant when the key is known to all parties.
- bitexploder 4y agoSure. That is DRM and obfuscation in a nutshell. How annoying can I make this for you to reverse engineer?
- toast0 4y agoObfuscation with encryption can be done with good ciphers, like AES, but the key is still shipped with the code, so it's still just cat and mouse. It's a little different if the key is hardware specific, so each binary only runs on one system and it's hard to extract the keys, but that's not a typical setup. Usually it's this code needs to run on the general public's computers or phones, and that's too general a target to rely on hardware crypto.
