Quick question, if encrypted data looks like noise, how can you tell apart 256-bit encrypted noise and 512-bit encrypted noise?

- raxxorrax 5y agoI don't think you can with a decent crypt. In practice most encrypted containers come with metadata and a header describing the type of encryption since the assumption is that it can only be decrypted with a key anyway. If you forget encryption parameters, this can become difficult even if you have the key. In cryptanalysis it is normally assumed that the attacker knows the algorithm and encryption parameters aside the key.
- drran 5y agoIt's dead simple: «You used encrypted connection today. It's encrypted with 10000024 bit key, which is forbidden by China. You can send your key to us to prove that you are innocent, or go to jail.»
