Is it possible to make a git commit non-amendable?

Question

Is there a way to protect a given git commit from being amended?

All I can think to do is to write a pre-commit hook to check the SHA against a list of 'non-amendable' SHAs. Does anyone know of a standard/better way?

Thanks.

Answer 1

You can consider signing your commit with a GPG key.

In order to do so

• Add your GPG key as a signing key

  git config --global user.signingkey YOUR-KEY
  

• Commit using the -S option

  git commit -S -m "Your commit message"
  

Answer 2

You can tag commits using a private key so that if the commit is amended no one without the key can sign the new commit.
