PKCS-11 compile option for OpenVPN

[bob@afrinet.eu]

I wanted to know why compile options used in OPNsense (and pfSense®) didn't include pkcs11 ?

What is the reason ?

And what would you recommend for stronger authentication method / physical (like smart card ok USB dongle) ?

The optic is a large scale VPN where we would need to push dynamic routes && get strong authentication (firewall to firewall).



Actual OpenVPN compile options are as follow :


root@FW1:~ # openvpn --version
