Cryptography is not dead, but useless. We are heading in direction where just possession of random data will be criminal offense.

- eli 13y agoHow do you mean?
- ReidZB 13y agoI'm not the OP, but: Securely-encrypted data is supposed to be indistinguishable from truly-random data --- this is the widely-used definition of security for encryption. If laws are in place requiring that a user reveal any decryption keys upon a court order, then a truly-random file will "look" encrypted and so you may be ordered to provide your key to decrypt the file. Of course, it is truly random, and there is no key, so you would be in contempt of court. Indeed, assuming secure encryption, there is no way to prove that a truly random file is not actually encrypted. In an extreme case, where the state outlaws secrets entirely, possession of truly-random data will look like you are attempting to hide secrets.
- AnimalMuppet 13y agoAlso note that truly random data can encrypt other data simply by XORing it. That is, truly random data can in fact be a cryptographic key, if you use it as one.
