    77The 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.  Here's the details of the origin of the convergence secret: [https://tahoe-lafs.org/hacktahoelafs/drew_perttula.html Convergence Secret Justification]

     11All 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.
