Hi Jakob and thanks for your response. I don't know if a "are you sure?"
kind of confirmation question would add so much to the overall security.
I agree that the utmost security of the signer itself is the key factor
when designing a secure signing system.

This being the case, one should consider very carefully how to arrange
the management access to the signer server. If a single administrator is
able to log in to the signer and gain root privileges, he or she becomes
quite an attractive target...
