It is one of my pet peeves that people try to map
the digital signature operations of sign/verify
onto the privacy operations of decrypt/encrypt.

Writing a text book that even suggests this "duality" should be a
punishable offence.

For most public key systems the operations are
quite different,

I once heard a talk where the speaker defined signatures as "an encryption
scheme where you encrypt with the private key instead of the public key",
and then went on to note that there were some strange systems such as
DSA where you couldn't actually encrypt with the public key.
