We just had a death in close family and another terminally ill, so life is a party! I have run tests on .rar files i have made under known conditions. As it stands for now, I can (as expected) find the password just fine with a single file. With multiple files I have no luck, no matter whether I do. I have put all the hashes in the same file, and john does recognize them as different salts but cannot find the right pass. As said previously, the hashes from each file are different. WinRar obviously knows what part of the hashes to use, but do we have anyway of finding out?
