What happened:

I tried checking out a keybase encrypted git repo. It fails with a Could not fetch host key error.

What I expected to happen:

Honestly, I'd be a bit surprised if this worked out of the box. Keybase encrypted git uses git-remote-helpers (https://keybase.io/blog/encrypted-git-for-everyone) which may require a bit of extra work on SparkleShare's part.

This happens when:

1. Sync remote project
2. Own server
3. Address: keybase://team and Remote Path: /my-team/my-repo

If keybase repos can be supported, it would be best if they had a pre-configured checkout, similar to what exists for Bitbucket, GitHub, and GitLab.

To support the address no problem, to implement the helper is difficult. Because keybase uses for that a golang script, that means we must check if the host system has golang installed and must pull all requirements. SS uses pure git and for encryption openssl, what every system has pre installed.

That's totally fair and makes sense. Thanks for the reply! Feel free to drop this issue if it feels like something SS can't support.
