Below is the patch I posted to tech-crypto in August. I know Jason has tried it; last call for feedback before I commit this, too... Please send me an explicit cc: with any feedback.
After thinking about this a little bit, I think I would like for the libcrypto stuff to only use /dev/crypto if acceleration hw is available for the requested algorithm.
This is because using the kernel for the sw crypto is a neat little way for things like ssh to cause a kernel thread that will not be preempted to suck up a lot of CPU time. I'm not sure I like that very much.
Is this pretty easy to handle in the OpenSSL "engine" support?
