A quick PSA for those using Mac OSX with homebrew or a Linux variant with apt-get: There are two versions of gpg on homebrew. If you're like me, you installed gpg with: brew install gpg or sudo apt-get install gpg However this gives you: $ gpg --version gpg (GnuPG) 1.4.18 ... What you probably want is: brew install gpg2 or sudo apt-get install gnupg2 This gives you: $ gpg2 --version gpg (GnuPG) 2.0.26 libgcrypt 1.6.2 ... This is probably what you want, as it's the stable version. There's no harm in using gpg 1.4.x; the docs indicate that this is maintained because of its use on older and embedded systems, and AFAIK there's no reason to suspect gpg 1.4.x's security if you trust 2.0.x. It's just that the 1.4.x version has fewer features. I haven't tried other package managers, but I suspect they also have this minor pitfall.
