Exactly. I interchanged the terms. Weird. Shouldn't public
be "public"??? Thank you for clearing this up. There are
the other two questions still open ;) :

- Does libcrypt do the job? I guess so...
- The CAD data may contain a fixed header, so an atacker knowing
  the header might use this info to easily get the private key?

Thank's and Salam,
