initialize-gpg.sh

# Create a new GPG keyring
gpg -K

# Change ownership of the GnuPG directory
sudo chown -R $(whoami) ~/.gnupg/

# Change directory permissions so that only the owner has read/write access to files and enter into the directory
sudo find ~/.gnupg -type f -exec chmod 600 {} \;
sudo find ~/.gnupg -type d -exec chmod 700 {} \;

# Test the permissions
gpg -K
