Digital Signing (Beat The Dead Horse) was Re: Free Software …

The inherent issue with signing messages is trusting a third party.
(Supposing that third party can even keep everyone's keys straight.) That
third party, IE verisign, is unfortunately the only way to verify a key.
Personally, I wouldn't put any level of trust into anyone but myself when it
comes to my system security, and validating the authenticity of data.

OK, I get a message. It's signed. How do I verify the authenticity of
the signature? Against what database? If User X writes a message, sends
it ostensibly from Derek, and signs it with a bogus key, how do I know
that, unless I already have Derek's key... and in fact some huge database
of keys somewhere... it sounds like a data management nightmare, how is
everyone supposed to keep track of everyone else's keys???

Still not getting it,
