Project Description

It is possible to sign (off) git commits with your SSH key. The very same key that's used to sign in to SSH servers. I would like to look into the buffer contents in the two cases and examine if/how they are replacable. (I.e. sign a commit during ssh authentication.)

Goal for this Hackweek

Show that sshd cannot sign git commits.

      Finished. I found no way how to confuse the signing/authenticating protocol. Details in "slides".

    Port git-fixup to POSIX shell script and submit to git/git by mcepl

    Description

    https://github.com/keis/git-fixup is an exceedingly useful program, which I use daily, and I would love to every git user could bask in its awesomeness. Alas, it is a bash script, so it is not appropriate for the inclusion in git proper.

    Goals

    Port the script to plain POSIX shell and submit for consideration to git@vger.kernel.org
