While I mostly agree about the hostility of tools like openssl(1), I
don't think it applies overly much in this context. The use model I had
in mind when creating the x509 support was:
(1) The person responsible for the a bulk build creates a CA
(2) An intermediate key with a short valid time (3 month?) is used to
sign the packages.
(3) The CA certficate is published in the same location as the packages.
Either a signature from a TNF "master" certificate or a PGP/GPG signature is
used to anchor the trust.
For the user this means doing the trust verification once -- either for
the TNF "master" CA or the bulk builder certificate. This can happen
using the normal PGP/GPG tools, netpgpverify or whatever. Afterwards,
she doesn't have to care about the mechanism used.
For the bulk builder this means (a) setting up the personal CA (b)
creating the signing key on a regular base. You can find a script for
doing that with two calls. Look at pkgsrc/pkg_install/files/x509. Might
need some more polishing, but I don't think there is much complexity
