yeah, seems to be an OpenVPN issue rather. Padlock works with openssl speed and clearly accelerates stuff. Also I have set "SSLCryptoDevice padlock" in my apache https configuration and that works, too.

epia# openssl speed -engine padlock -evp aes-128-cbc

Bug #2258: engine padlock broken in openssl on current master
http://bugs.dragonflybsd.org/issues/2258

Author: Jan Lentfer
Status: Closed

Target version: 

After Upgrading to  v2.13.0.527.g95bf5 openvpn does not work any more 
with "engine padlock" enabled in server.conf.

Seems engine padlock in openssl is broken. If I comment out "engine 
padlock" from server.conf, handshake works fine.

I X-ed out private info in the certificates.
