Building GnuPG from source was a simple matter of
the code, unpacking, then running the usual configure, make, and make
Using the code was easy, a quick pass through the
GnuPG Mini-Howto document showed how to create a key, and perform
simple encryption and decryption of a file.
A wealth of documentation is available online including numerous
Stable version 1.4.2 of GnuPG was
It features a number of changes to the ID card software, new
command completion capabilities, improvements to the key cleaning
function, and more.
If you should need any encryption capabilities, from simple secure file
trading to complicated security systems, GnuPG is there to help.
