Thanks for your reply. Let's assume the following: You would be also
a german national, we both are friends and would have bad things in
mind...

I issue now fake signatures (from a german CA) to our fake keys* and
then we would start some bad business on the Internet. How could
customers, not pros like all you guys here on the list, could verify
that we both are the persons the keys/signatures are claiming?

* Due to my stupidness i no longer have access to my passphrase
nor can i find my rev cert, in case someone would use my key,
which i used here for signing previous post from me.

Regards
Stefan
