send PGP signed commits/patches with git-send-email(1)

Hi,

In Kernel Recipes this month [1], Greg mentioned that git-send-email(1) could be used together with gpg(1) to verify authenticity of the sender.

I couldn't find any documentation about it, and if I create a patch from a commit that was signed (-S), the PGP signature is not part of the patch.

So, is there a way to PGP-authenticate patches? If not, could this be added to git(1)?

$ git --version git version 2.36.1

Thanks,

Alex
