Possible to GPG sign commits by default?

[Brandon Phelps]

I've got SourceTree (on Mac) set up with GPG and I can sign my commits fine by manually selecting "Sign commit" from the commit settings dropdown, but this is tedious when you do a lot of commits.  Is there an option hiding somewhere that I can use to force SourceTree to sign ALL of my commits, on either a global or repository level? (either would work for me)

I did try editing my global .gitconfig as well as my repository config with a new section:

[commit]

gpgsign = true

And this works fine when I git commit via the command line, but SourceTree isn't even able to commit at all with this settings since it tries to open /dev/tty for some reason (even though my pinentry program is set to pinentry-mac).

Any help would be appreciated!

To be able to sign commits by default, in your ~/.gitconfig, add:

[user]
    signingkey = ........
[commit]
    gpgsign = true
[gpg]
    program = /Applications/SourceTree.app/Contents/Resources/bin/stgpg.sh

Check stgpg.sh to see why this resolves the issue with /dev/tty.

Worked perfectly for me, thanks a LOT!

Sorry for the stupid question but... in `signingkey` what should I put? The fingerprint?

[Guillaume Boudreau]

You need to use the key ID; its 8 hexadecimal characters, which I think are (always?) the last 8 characters of the key fingerprint.

Thanks!

On my Mac, with Homebrew installed gpg and pinentry-mac, the following git configuration was sufficient:

[user]
 name = My Name
 email = xxxxx@users.noreply.github.com
 signingkey = XXXXXXX
[credential]
 helper = osxkeychain
[commit]
 gpgsign = true
[gpg]
 program = /usr/local/bin/gpg
