lighttpd2

The minimum configuration file for lighttpd2 should contain the following.

    module_load [
        "mod_gnutls",
    ];

    "pemfile" => (
        "key" => "pkcs11:model=SoftHSM%20v2;manufacturer=SoftHSM%20project;token=System%20softtoken;type=private",
        "cert" => "pkcs11:model=SoftHSM%20v2;manufacturer=SoftHSM%20project;token=System%20softtoken;type=cert"
     )

The exact PKCS #11 URLs can be seen using

p11tool --list-all --login pkcs11:model=SoftHSM%20v2;manufacturer=SoftHSM%20project;token=System%20softtoken

Before running ensure that the user lighttpd2 runs with is on the pkcs11proxy group.
