Support encryption of admin secrets

Please add crypt to repo. GPG2 will be great.
Many users would use git on cloud but without strong encryption this will be not possible

Hi! Just wanted to clarify, do you mean encrypting the repos at rest, gpg signing the commits to the admin repo, or something else?

Encryption at rest unfortunately isn't easily possible since this verifies the path and permissions then simply shells out to git.

That looks like it could be a good solution for storing things like what's in the admin repo - I'd welcome any PRs.
