What's the secret?

[Paul Rabahy]

There are 2 secrets.

The first is the FURL. This secret protects access to the grid. Anybody
with the FURL can talk to the introducer and see all the nodes on the grid.
Once they know about the nodes they will be able to upload files.

The second is your CAP(s). Each file that you upload to the grid gets a
CAP. Anybody with the CAP will be able to verify/decrypt/modify the file on
the grid corresponding to the CAP. The CAP has several different forms that
allow more granular access control (Read Only vs Read/Write). Most people
will end up saving a CAP as an Alias so that it is easier to use on their
local machine.

Hopefully this helps clear it up.
