bcrowell writes "The latest CryptoGram reports that AES (Rijndael) and Serpent may have been broken. The good news is that when cryptographers say 'broken' they don't necessarily mean broken in a way that is practical to exploit right now. Still, maybe we need to assume that any given type of crypto is only temporary. All of cryptography depends on a small number of problems that are believed to be hard. And all bets are definitely off when quantum computers arrive on the scene. Maybe someday we'll look back fondly on the golden age of privacy."
