Welcome to the gpg4usb project

gpg4usb is a very easy to use and small portable editor to encrypt and decrypt any text-message or -file you want.

Our aim is, to give anyone the possibility to send and receive secure encrypted messages anywhere - on any computer out there, no matter if Microsoft Windows(TM) or Linux is running on it. Therefore it's usage is self-describing, and the user-interface as simple as possible.

gpg4usb is free software, and it is licensed under the GNU General Public License (GPL).

If you want to give it a try, please get our latest release here or visit our download section, get the files and unzip it onto your usb-pendrive... et voilĂ : you're done and ready to go!

New stable Release 0.3.3

  • gpg4usb-0.3.3 fixes a bug which made private key export impossible, when gpg4usb was started from a path containing non ascii characters
  • this release contains greek translation, thanks a lot to George
  • the gpg.conf was modified according to the apache gnupg recommondations to avoid the use of sha1
  • we have bundled gnupg 1.4.16 with release 0.3.2-1. This gnupg version fixes a DoS Bug, see announcement 0.4.15, and also an interesting attack, which allowed to sniff a private key with a mobilephone ;-) look at announcement 0.4.16

FAQ & Known Bugs
We now have a FAQ and Known Bugs section on the website, please have a look on these before asking for support.

Some people told us that they like gpg4usb and would want to donate. We are happy if you enjoy gpg4usb, and about your feedback. If you want to donate we would be happy if you support Frontlinedefenders, as they could do better things with the money, and, you know, they provided us with the mac mini :). You could also take part in the fund raising campaign for gnupg on goteo.org if you have some money to spend.
