In my various attempts to get the gnupg related modules working on CPAN
I came up with two options Crypt::OpenPGP which is in general slow
because it attempts to do things in Perl, and GnuPG::Interface which
worked almost perfectly but we were using it in a weird fork model kind
of way, for doing a single encrypt/decrypt run at a time it worked
brilliantly. Having said that, one caveat, my analysis was done in early
2003.
I would suggest giving GnuPG::Interface a go because it handled calling
out to 'gpg' most "correctly". Meaning it uses the status-fd, logger-fd
options properly which is the preferred way to call gpg in an automated
fashion.
Good luck,
