Auto sign your git commits

git-auto-sign-commits.sh

# generate a new pgp key: (better to use gpg2 instead of gpg)
gpg --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

# export private key in gpg:
gpg --export-secret-key -a "your_username"

# export public key in gpg:
gpg --armor --export your_key_id
# your_key_id is the HASH id in front of `sec` in previous command.

# set a pgp key for git:
git config --global user.signingkey your_key_id

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

# auto sign your commits globaly
git config --global commit.gpgsign true
