Signing is a very different thing than encryption.  It has nothing to do
with encryption.  Using the terms decryption or encryption to describe
signature creation and verification leads to confusion (it is actually
only partly true for the RSA algorithm).

We use two different keys, one for encryption and for signatures.
OpenPGP merely puts them together on the same "keyring" (technically
called a keyblock) for convenience.



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
