Privacy, Security, Encryption Researchers have found a weakness in the AES algorithm. They managed to come up with a clever new attack that can recover the secret key four times easier than anticipated by experts. In the last decade, many researchers have tested the security of the AES algorithm, but no flaws were found so far. The new attack applies to all versions of AES even if it used with a single key. The attack shows that finding the key of AES is four times easier than previously believed; in other words, AES-128 is more like AES-126.

So AES-256 is more like AES-254. I'm sure most users of AES-256 can live with that?

Actually some experts believe that AES-256 is easier to crack than AES-128:
