-What Is It?
------------
-
-A file's capability is derived from two pieces of information on
-upload: The content of the file and the upload node's "convergence
-secret". By default, the convergence secret is randomly generated by the
-node when it first starts up, then stored in the node's base directory
-(<Tahoe's node dir>/private/convergence) and re-used after that. So the
-same file content uploaded from the same node will always have the same
-cap string. Uploading the file from a different node with a different
-convergence secret would result in a different cap string—and in a
-second copy of the file's contents stored on the grid. If you want files
-you upload to converge (also known as "deduplicate") with files uploaded
-by someone else, just make sure you're using the same convergence secret
-as they are. 
-
-The advantages of deduplication should be clear, but keep in mind that
-the convergence secret was created to combat snooping. For example, with
-a convergence secret and a file, I can generate a file capability that
-would allow me to determine that you have uploaded a file to the grid.
-This isn't a big deal for things that are personally produced, but is a
-big deal for commonly known things that you want to keep secret that you
-know about. Examples would be a Bible in China or The Anarchist's
-Cookbook at the High School that I went to.  This is called the 
-"Confirm-The-File" attack.
-
-There is one more way that this can be used.  Let's say that you know
-somebody stores their W-2 (a US tax document) on their Tahoe-LAFS grid.
-You can, with a little script, try various numbers for identity information
-and eventually end up with your full identity and salary.  This is called
-the "Learn-The-Remaining-Information" attack.
-
-Here's the details of the origin of the convergence secret:

-What If I Change My Convergence Secret?
----------------------------------------
-
-All your old file capabilities will still work, but the new data that
-you upload will not be deduplicated with the old data. If you upload all
-of the same things to the grid, you will end up using twice the space
-until garbage collection kicks in, if it's enabled. As one user put it,
-it would move the node where you change the convergence secret into a
-new deduplication domain.
-
-How To Use It
--------------
-
-To enable deduplication between different clients, **securely** copy
-the convergence secret file from one client to all the others.
-
-For example, if you are on host A and have an account on host B and you
-have scp installed, run: 
-
-  *scp ~/.tahoe/private/convergence
-> my_other_account@B:.tahoe/private/convergence*
-
-If you have two different nodes on a single computer, say one for each
-disk, you would do: 
-
-  *cp /tahoe1/private/convergence /tahoe2/private/convergence*
