Blob encryption will be live when I put this folders update out. The current version just uploads publicly. Give me a few days so I can make sure the implementation is solid (works great though, I'm using it on my dev machine right now) :-)

It could be cool if our apps can be interoperable. And so we should write a Nip together.
