The OpenVPN option text should probably be renamed. The engine command in OpenVPN isn't required. When it's unset then it automatically selects a device which supports accelerating whatever cipher it's trying to use.

When it's set to a specific engine, it's supposed to prefer that engine but I don't believe it's restricted to only using that engine. Since most things only have 0-1 available usable engine types, that's not so easy to test.

So really the No Hardware Crypto Acceleration line should be Use any available cryptographic hardware device or something along those lines.

@stephenw10 Thanks for the response. I am sure that the life cycle for the my APU is pretty much done. She has served me well, but considering that I will probably be looking to use squid and suricata, it might be time for me to bite the bullet and upgrade accordingly.
