Is it something I can take advantage of?


This is software cryptography pseudo-driver working without any real 
hardware acceleration. It is used by IPSec, geli and some other 
subsystems when there is no any hardware cryptography accelerator 
present in system.

This is the crypto(4) driver. It provides a device-independent framework
to support cryptographic operations in the kernel. I.e. is uses hardware
if available. If not it uses software, like in this case.

One use of it is encrypting disk partitions with geli(8).
