In order to prove that I had a signature on a commit I needed to use a this command line command:
$ git log --show-signature -1
I could not get Magit to display the signature I tried to use the Magit Key (l) and the -S switch.
But could not see the signature details.
Addressing questions to the answer from the magit author
I ran out of space in my comment so I edited my question to reply.
So I validated that each commit was signed using
git log --show-signature| cat in my shell in Emacs. Then I redid the command above and looked at individual rows to see the signature - but even when I hit RET as you say above, the signature . I could also not see any evidence when all of the signatures were applied that any of them were signed.
How do I configure the expanded view of the signature so that the RET key will cause the details of the signature as the
--show-signature flag requires? I most want to be able to drill in with
RET and see exactly the text that is needed. I am concerned that I am missing details in magit that the shell shows properly.
