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 0.3.3-1
