"GnuPG supports reading a trust "map" generated by an external process
that can use whatever trust rules it likes."
This requires another piece of software (or programming skills). I
don't know of any software that does this, and i lack programming
skills. So this solution is not for me :(
I'm not a cryptographer, however I think that those issues are
serious, because as we know, algorithms that are now considered
secure, will probably become broken one day. While this most likely is
not going to happen overnight, suddenly and unexpectedly, it could be
still good for users to enforce their policy regarding minimal
strenght of algorithms accepted by their web or trust., or if person
is using "direct" trust model, it could be useful when person is doing
--check-sigs (or check in the --edit-key shell), to display
signatures, along with their algorithms, and signers key/uid validity,
to have enough confidence when setting validity of keys/uids signed by
other people. Of course new versions of GnuPG could enforce minimal
strength of algorithms, however it doesn't allow users to decide about
confidence/security level, so in my opinion GnuPG should only set sane
defaults. Also it will allow someone who is still using older version
of GnuPG for some reason (like older packages in distributions
repository) to use strong enough algorithms to verify authenticity of
Should i crosspost the first message of this thread and this one to
gnupg-devel? Or maybe i should contact Mr. Koch directly?
Werner if you read this thread please reply. Thanks.
