Tooling for verification of PGP signed commits
This is an incomplete work in progress, but currently includes a pre-push hook
script (pre-push-hook.sh) for maintainers to ensure that their own commits
are PGP signed (nearly always merge commits), as well as a script to verify
commits against a trusted keys list.
Using verify-commits.sh safely
Remember that you can't use an untrusted script to verify itself. This means
that checking out code, then running verify-commits.sh against HEAD is
not safe, because the version of verify-commits.sh that you just ran could
be backdoored. Instead, you need to use a trusted version of verify-commits
prior to checkout to make sure you're checking out only code signed by trusted
keys:
git fetch origin && \
./contrib/verify-commits/verify-commits.sh origin/master && \
git checkout origin/master
Note that the above isn't a good UI/UX yet, and needs significant improvements to make it more convenient and reduce the chance of errors; pull-reqs improving this process would be much appreciated.
