I’ve been talking about this for a while, but I finally got around to doing it. I’ve put together a software package consisting of Firefox Portable, GNU Privacy Guard, and FireGPG. I’m calling it “CryptoFox”. You can download it here.
The idea behind this is to lower the barrier to entry for using PGP encryption. If you want to communicate privately with someone, instead of having to guide them through the install process for 3 different components, you can just have them download CryptoFox and run it. No installation is required.
It’s also a little tricky to set FireGPG and GnuPG up to function portably. If you want to run them from a USB stick on any computer, I’ve already done the hard part for you.
