Git GPG Setup Script for macOS

This script installs and configures GPG (GNU Privacy Guard) on a macOS machine and configures Git to use GPG to sign commits.

Prerequisites

• Homebrew must be installed on your machine. If it is not, you can install it by running the following command:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

How to use the script

1. Download the script from this link and save it as git-gpg-setup.sh.
2. Make the script executable by running the following command: chmod +x git-gpg-setup.sh
3. Run the script by entering the following command: ./git-gpg-setup.sh

The script will do the following:

• Check if gpg is installed and install it if necessary.
• Check if pinentry-mac is installed and install it if necessary.
• Generate a GPG key.
• Configure Git to use your GPG key.
• Create a gpg-agent configuration file.
• Ask the user how long they would like the gpg-agent to cache the password.
• Configure Git to automatically sign commits with your GPG key.

The script will also verify the configuration by creating a local test git repository, making a commit, and verifying the signature of the commit. The test repository will be removed at the end of the verification test.

If the signature and GPG key are displayed correctly, then your configuration is working as expected.
