That's not what I'm saying. Let's say you have a file that is plain, not encrypted. Then you have the same file that is encrypted. One can use the info from the not encrypted file to hack the encrypted one. The keys have nothing to do with it. At least that is my understanding of it. Like I said, if you are 100% sure, don't worry about it. Just send some encrypted and some not. If no one can hack it, no problem. If you're wrong tho and you are sharing info someone wants, well, you get to keep the pieces. Dale :-) :-)
