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 voilà: you're done and ready to go!

We received some hints that the default key generation settings are not sufficient anymore. Gpg4usb was still generating DSA/El-Gamal Keys. Here is a press report of an experiment breaking a 932bit El-Gamal Crypto Key with 21 personal computers (252 cores) in 148.2 days [link].

So we finally put out a release which generates safer keys by default. Also it was suggested to us that keys should expire by default, as they may get closer to beeing breakable with time. So we now set a default expiration date of 5 years. You could still change this setting yourself.

Changes:

Updated included gpg binary to version 1.4.12
In key creation we changed the following
- Set keytype to RSA instead of DSA/El-Gamal
- Set expiration to five years by default
- Set minimum keysize to 1024 bit

Bugfixes:

Fix creation of empty Windows registry key on import from existing GnuPG
