Gnu Privacy Guard, an open source crypto tool compatible with OpenPGP and laterally supporting dozens of different uses is trying to raise funds for a few months of some additional developers time. I use GPG daily, including signing and encrypting my mail, securing online chats, keeping my password store safe, and so much more. Please check it out and help if you can. If you want to know more ways to use GPG, find me on Freenode at #cmdln or keybase.
