I would like to introduce the HIBPOfflineCheck plugin for Keepass  to
factory. It allows users to check the Keepass databases and newly added
passwords against a local copy of the Have I been Pawned  database, or
optionally also against the web service.
The package has been in the Mono repository  for a while and with its small
codebase does not require significant effort for me to maintain, even though I
read the diff for each release.
