Hi!

I'm interested in using dm-crypt to do full-drive encryption, but do
not want my processor to be stuck doing the encryption.
Unfortunately, it does not support the aes-ni extension.  As an
alternative to upgrading, I was wondering if dm-crypt supports a sata
controller card that "supports aes-256".  An example can be found
here...

Would I be able to offload the encryption to the add-in card's chip?

Thanks!
