Welcome to GnuPG 2.2



Installation Instructions


Double click the Install package to install GnuPG 2.2. Any previous version of GnuPG 2.2 will automatically be uninstalled during the installation process. Do not install GnuPG to any target other than your “Macintosh HD” device.



Converting existing Keyrings


If you do not intend to use your keyring with GnuPG 1.x or 2.0.x in the future, we recommend that you convert your keyring to the new GnuPG 2.2 format. This will speed up any keyring operations. However, the drawback is that your keyring is not compatible to GnuPG versions before 2.2.


To convert an existing pubring.gpg file to the new keybox format, a helper tool is provided. Simply execute


Verifying the Download Integrity


The SHA-256 sum of the downloaded file (e.g. GnuPG-2.2.0.dmg) can be verified as follows.

1. Open a Terminal window 

2. Execute: shasum -a 256 Downloads/GnuPG-2.2.0.dmg

4. Compare the checksum you got in the Terminal with the SHA-256 sum on the web page.


Verifying the Package Signature


In addition to the developer signature verified by Mac OS X, the Installer Disk Image also contains an OpenPGP signature which can be used to verify the Installer package. To verify the integrity of the installer, download the package signature file (e.g. GnuPG-2.2.0.dmg.sig), then open a Terminal window and execute:


gpg2 --keyserver pool.sks-keyservers.net --recv-keys 0xDB1187B9DD5F693B


gpg2 --verify GnuPG-2.2.0.dmg.sig GnuPG-2.2.0.dmg


The 1st command will download and import the public key that you need in order to verify the signature; the second command verifies the signature.
