This software already exists. Take a look at Disperse/Collect at http://www.eskimo.com/~weidai. Disperse splits a file into n base64 encoded pieces where any k of them can be used to reconstruct the original. Collect will search through arbitrary collection of files (for example the entire news spool) for these pieces and automatically reconstruct everything that it finds.

Could something akin to this be a practicle method or test for Blaze's "Key Escrow without Escrow Agents"? The main thing lacking is a secure method to get it out to the different escrow servers... (One could just encrypt each chunk of the message/key in a server's public key... Servers would read that newsgroup and pull down and escrow the chunks that they recognize.) _______________________ Regards, When we ask advice, we are usually looking for an accomplice. -Marquis de la Grange Joseph Reagle http://farnsworth.mit.edu/~reagle/home.html reagle@mit.edu E0 D5 B2 05 B6 12 DA 65 BE 4D E3 C1 6A 66 25 4E
