For all of my projects, I now I put this script in .git/hooks/post-commit and post-merge: #!/bin/bash -eu if ! git log -n1 --show-signature | grep -q 'gpg: Good signature' then yes "FORGOT TO SIGN COMMIT MESSAGE" exit 1 fi So anytime I forget to sign, I get an obvious error and can immediately run git commit --amend -S. To automatically add a script like the one above to all new projects (plus quickly add it old current projects), you can follow these instructions: http://stackoverflow.com/questions/2293498/git-commit-hooks-global-settings > If you're really serious about it, you should probably reject pull > requests without signed commits; otherwise, signing becomes > meaningless because only honest authors do it I find signing my commits quite useful even on projects without a default signing policy because it lets me diff from the last time I provably reviewed the code. Here's my script for that: #!/bin/bash -eu KEY=F29EC4B7 last_signed_commit=$( git log --topo-order --show-signature --pretty=oneline \ | grep -m1 " gpg: Signature made.*RSA key ID $KEY" \ | sed 's/ .*//' \ | grep . ) || { echo "No signed commit found. Dying..." ; exit 1 ; } set -x git diff $last_signed_commit By diffing against the last signed commit I made, I also review any commits that were made using my name but which I didn't actually make, such as squashes and rebases of my commits (and, of course, forgeries). For anyone who's bored and wants to read a lot of text, I think the definitive work on git signing is this: http://mikegerwitz.com/papers/git-horror-story.html -Dave -- David A. Harding
