The successor to the DES encryption algorithm, AES can run with a 128-, 192- or 256-bit key to encrypt. How long will it be until AES is obsolete? Possibly never. There are 340 billion billion billion billion 128-bit keys; if you had a billion computers, each one of which could crack a billion keys a secondit would still take more than 10 trillion years to try all 128-bit keys.
