I have written the following article about using GnuPG on i. This article was originally published on System iNetwork which is gone, but my raw manuscript can be found here:

• Download Version 1.4.10 (3.2 MB)

Note: Scott Klement does not claim any ownership or rights to GnuPG, he has only compiled it, and provided the compiled version for your convenience.

For license, official documentation, source code, and other resources related to GnuPG, please visit their official home page at GnuPG.org

To install GnuPG on IBM i, please take the following steps:

• Download the (above) file to your IFS. You may download it to your PC, and copy it to the IFS via Windows Networking, or FTP in binary mode, or any other method that seems appropriate.
• I recommend placing the download in the /tmp directory of the IFS. For the sake of example, /tmp/gnupg-1.14.10.tar.Z
• Sign on to a 5250 screen.
• Enter PASE by typing: CALL QP2TERM
• Type: cd /
• Type: uncompress /tmp/gnupg-1.14.10.tar.Z
• Type: tar xf /tmp/gnupg-1.14.10.tar
• Type: /qopensys/usr/local/gpg/bin/mklinks

The best source for GnuPG documentation is their documentation page.
