We are setting up our first EDI system that relies on incoming and outgoing file encryption using OpenPGP. The incoming files that are encrypted with our public key, we can successfully decrypt using our private key using Gpg4win's command line option. How to work with PGP keys using GnuPG. To generate your key pair, we'll work from the command line. Open a terminal window and issue the following command: gpg -gen-key.
