vc doesn't know anything about signing commits. magit does, though. If you're willing to have all your commits signed you can set commit.gpgSign in your git configuration file.

  • I'll use commit.gpgSign in git local configuration then. That solves my problem. Thanks!

  • Does it ask for passphrase? Mine is failing because there is not tty to ask for passphrase.

    @Jangid, you should look through the existing questions on how to use gpg with emacs, I'm certain this has been answered before.

  • @rpluim, my gpg is working fine with emacs. I can encrypt files with .gpg extension, I can sign and encrypt emails. But only vc things are not working with gpg. As a workaround what I do is this. I run a pull request on cli, enter passphrase and because the ttl is set to about 10 mins, vc-next-action works without going into passphrase phase.

    @rpluim, normally, when I encrypt/sign emails or open .gpg files I get a prompt in mini-buffer at the bottom. Because of (setq epg-pinentry-mode 'loopback). But for vc, as you said, I get a prompt outside emacs. And on MacOS that is somewhat mangled so I cannot enter passphrase. Not Sure why I am not getting the prompt in the minibuffer like in the case of normal file encryption etc.
