It has it's asm inline but be wary of any encryption algo and always confirm that it is the right thing (by comparing the bytes of other implementations.

Hi,
I've recently switched to dmcrypt with aes cipher, which works quite well except for beeing a little bit slow (~40mb/s read/write), where even weaker CPUs in an old comparison I found yield ~60-80mb/s.
A few times AES586 is mentioned beeing a hand optimized assembler version of the generic AES module, but I wasn't able to find it. Is it not part of the Fedora15 default kernel, or has it been removed from vanilla as well?

Similar name but that's not the same thing - this is part of the OpenSSL project.
The module Clemens was asking about is a kernel module that provides
arch-specific acceleration for the in-kernel crypto API.

It was there as a module in the f15 GA i686 kernel package:
