Yes, it's pretty good privacy, implemented to the GNU privacy guard. It's a long thing.... But it's a very reliable and very well-known system outside of government in the technology community, and I would like to see it or some kind of variant used in government. It's another level of security to have PGP signed emails with a trust ring, where I've sign your key and you've signed my key.
I'd like to at least have the government explore that, if that's possible.
