[Q] Encrypted GIT?

Hi, list!

I want to create a private GIT repo (without working copy) on a
machine in external data-center. While I do not actually believe that
it is possible that someone who has physical access to a machine would
be interested in peeking into my repo, I'd like to play safe and to
have this issue covered.

Please advise what is the best way to do it. Are there any existing solutions?

Thanks,
Alexander.
