Greatly improve usability of GPG for all operating systems
Users increasingly are trying to use GPG or PGP to verify our software. This is a great trend to encourage. Unfortunately, the current software available for Windows and OSX is clumsy or non-functional for users. Thandy may replace the need for this improvement, but people will still want to verify that thandy does comes from tor.
Help existing projects improve their usability for non-technical users.
Tor is becoming an introduction to GPG/PGP for many people and telling users to 'figure it out' on their own doesn't work so well. It makes users just not verify the software is actually from Tor, or they ask for less secure ways to accomplish the goal, like MD5/SHA-1 hashes of the packages.
