"AES-NI support, 256bit" algorithm.


We can use a new algorithm "AES-NI support, 256bit" as an Intel AES-NI encryption algorithm from 5.2.x.

However, the algorithm is NOT a FIPS compliant, I think.

And, as you know, according to NIST 800-57, NIST recommends more security algorithm, the details is opened as KB66237(

Generally speaking, all of algorithm NIST recommends is FIPS compliant algorithm, I believe.

So, I have a question.

I am afraid that the algorithm of not compliant FIPS does not adjust to NIST 800-57...

"AES-NI support, 256bit" has already adjusted to the NIST 800-57 statement?

Re: "AES-NI support, 256bit" algorithm.

The twovalgs are actually bit compatible, but one has been formally certified, the other has not. There's no difference between them cryptographically though.

Whether you need to be using a certified alg is up to your personal policy though.
