Associating GPG key with Git

Associating GPG key with Git

1. Use the following command to list the private GPG key you just created:
$ gpg --list-secret-keys --keyid-format LONG <email>

2. Copy the GPG key ID that starts with sec. In the following example, that's
32F2B65B9246B6CA:
sec   rsa4096/32F2B65B9246B6CA 2017-04-01 [SC]
      D5E4F29F3275DC0CDA8FFC8730F2B65B9246B6CA
uid                   [ultimate] User <email>
ssb   rsa4096/B7ABC0813E4028C0 2019-04-01 [E]

3. Tell Git to use that key to sign the commits:
$ git config --global user.signingkey 32F2B65B9246B6CA

   If Git is using gpg and you get errors like secret key not available
or gpg: signing failed: secret key not available, run the following command to
change to gpg2:
$ git config --global gpg.program gpg2

  If you don't want to type the -S flag every time you commit, you can tell Git
to sign your commits automatically:
$ git config --global commit.gpgsign true
