Re: Warning! New cryptographic modes!

For what it is worth, in the Tahoe-LAFS project [1] we simply use CTR mode and a unique key for each file. Details: [2] Tahoe-LAFS itself doesn't do any deltas, compression, etc., but there are two projects layered atop Tahoe to add such features -- a plugin for duplicity [3] and a new pro
