This is a git-remote-gcrypt encrypted special remote. Only sending files in to the remote works, and only for local repositories. Most of the work so far has involved making initremote work. A particular problem is that remote setup in this case needs to generate its own uuid, derivied from the gcrypt-id. That required some larger changes in the code to support. For ssh remotes, this will probably just reuse Remote.Rsync's code, so should be easy enough. And for downloading from a web remote, I will need to factor out the part of Remote.Git that does that. One particular thing that will need work is supporting hot-swapping a local gcrypt remote. I think it needs to store the gcrypt-id in the git config of the local remote, so that it can check it every time, and compare with the cached annex-uuid for the remote. If there is a mismatch, it can change both the cached annex-uuid and the gcrypt-id. That should work, and I laid some groundwork for it by already reading the remote's config when it's local. (Also needed for other reasons.) This commit was sponsored by Daniel Callahan.
