Here is an intriguing thing about this theory.  If we get it working, for files that use no splitting internally (maybe 500 MB or less) there would only be one crypto key.  If you could remember it in your head, you wouldn't even need any file!  Our program will have a crypto key direct entry mode.  You type in the crypto code from memory and your file is restored.  Why?  For total legal security of your documents!  

Under American law, if you go through the airport, anything you carry with you like your computer can be legally opened and searched.  If you put your iphone inside of a metal box with a key, that key can be demanded by the government because its physical.  But the law at this time won't allow the government to force you to give the contents of your mind.  So if you use a lock that requires a password, they can't make you give them the password by law.  Imagine zipping your top secret documents and then compressing them using our software.  Let's say your files are 450 megs, and our software's cut-off point for a single crypto key is 500 MBs.  So you get your crypto key, easily memorize it, and now you are carrying the entire 450MB file IN YOUR MIND.  Its like Johnny Mnemonic, only better, because all that data isn't actually in your mind!  When you go through the airport, you don't even need your computer, the top secret files are in your mind, safe from badguys, safe from the law should they try to use it against you.

So then you get to where you are going, download our software onto any computer you want, and use the "crypto key direct entry" mode and type in your crypto key following the format (x.yyyyy.z) and your document is recreated out of the ether for you!

It sounds like science fiction, but it just makes me feel exhilerated beyond words!  I can't wait to see this work.  It will be a true marvel.
