[Monkeysphere][] is a project to verify identities of sites using the
[[PGP]] web of trust.  For example, you can verifiy [[SSH]] keys using
the WoT, rather than by getting fingerprints directly from the server
admin (or however it is that you currently decide to accept SSH keys.
You don't just accept them without checking, do you? :p).  The
Monkeysphere [README][] has details on common tasks.

I've added a Monkeysphere ebuild to my [[Gentoo overlay]], as it is
not currently in the base tree.
