Re: File Encryption AES-128 versus AES-256?

While there are theoretical attacks on AES128, there have been none that are in any way currently practical. Assuming someone with the resources of the NSA wanted to look at your stuff, it will still take them Trillions of centuries to work on that (and little else).

If AES-128 is so insecure than AES-256, then why is it approved by the US Air Force as decribed the link I posted?

Dont understand.

I don't understand what you're saying. No. AES-128 is NOT considered insecure. Far from it.

The best published attacks take the relative security down by 2 bits, or say AES-126. Still not practical to attack, even with a global cluster of supercomputers.

As for standards? It's possible that a military would require far stronger encryption than what is currently strong. They might have an interest in keeping their secrets safe 20, 30, 50 years into the future.
