The Software needed For PGP Verification & Wallet Generation

Mac users. Check out this tutorial written by Jerzi J. Gangi on his website.

Jerzi shows how to install and configure PGP software for OS X. He is using it for email encryption but it will verify the wallet software as well. When you have verified the wallet software on your Mac you can go to Part 2 and continue from there.

You will also need these files:

1. Go to Github and download the wallet software.

2. Go to Canton Becker’s website contact page hereClick on the PGP Public Key link. (I didn’t link directly to it in case it gets moved).

3. Save Canton Becker’s public key block. Copy everything between and including —–BEGIN PGP PUBLIC KEY BLOCK—– and —–END PGP PUBLIC KEY BLOCK—–
