Source control with encrypted cloud backup

[BrightAnarchist]

So I've been using Mercurial and Bitbucket for a lot of my development, but I don't know if I trust bitbucket to not steal my source code. Given that, I was wondering: is there a good site similar to bitbucket that acts as a source control server, yet will store everything in an encrypted manner s.t. only I can access it (i.e. even the people operating the server cannot read the source)?

My thinking is that I should just establish my own local mercurial setup, and then regularly PGP up the full directory and backup the PGP file. It's probably the only way to accomplish what I want.
