I use dm-crypt to encrypt partitions. I am building a small office server from consumer (or pro-sumer) category hardware. It made me wonder, hardware-assisted encryption is a notion in the air for years, is it reality yet?
The two crytical points of my question are:
- Do the mainstream manufacturers (Asus, Gigabyte etc.) ship products with these (cheap) chips?
- Does the Linux kernel have a (reasonably old) implementation for the hardware and integration with dm-crypt?
Bonus: The same two question with TPM chips. Do manufacturers integrate them to their hardware already? Are they supported by Linux? Do they speed anything up? Do they have any performance advantage?
