Questions about support for AES hardware acceleration built into modern x86 processors.
As per this Wiki page - An Advanced Encryption Standard instruction set is now integrated into many processors. The purpose of the instruction set is to improve the speed, as well as the resistance to side-channel attacks, of applications performing encryption and decryption using Advanced Encryption Standard (AES). They are often implemented as instructions implementing a single round of AES along with a special version for the last round which has a slightly different method.
