Auto sign your git commits

git-auto-sign-commits.sh

# Generate new SSH Key
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

# Test SSH connection to github
ssh -T git@github.com

# Generate a new pgp key: (better to use gpg2 instead of gpg in all below commands)
gpg --full-gen-key
# maybe you need some random work in your OS to generate a key. so run this command: `find ./* /home/username -type d | xargs grep some_random_string > /dev/null`

# check current keys:
gpg --list-secret-keys --keyid-format LONG

# See your gpg public key:
gpg --armor --export YOUR_KEY_ID
# YOUR_KEY_ID is the hash in front of `sec` in previous command. (for example sec 4096R/234FAA343232333 => key id is: 234FAA343232333)

# Set a gpg key for git:
git config --global user.signingkey your_key_id

# To sign a single commit:
git commit -S -a -m "Test a signed commit"

# Auto-sign all commits globaly
git config --global commit.gpgsign true

# Delete keys
gpg --delete-key keyID1 keyID2 keyID3
