If the only concern is leaving sensitive data in the clipboard after
use, maybe pinentry could *accept* pastes, but then also clear the
clipboard after it was pasted into?
I understand that this still "encourages" people to put their
passphrases into the clipboard, but that seems to be happening anyway.
What if, upon accepting a paste, pinentry was to expand the dialog a bit
and show a warning that says something like:
Pasted! Your clipboard has also been emptied, so that your
passphrase isn't exposed to other applications. GnuPG recommends
never copying your passphrase to the clipboard.
