When you encrypt names for ident, the other host isn't supposed to be
able to figure out who is making the request. If the remote site has
a problem they can give the string back to the connecting site's admins
and then they can figure out who is causing problems.

If you are actually using ident for authentication, you don't want to use
the encrypted mode unless you are willing to modify applications so that
they can decrypt the ident strings.
