in reply to Privacy without Encryption

Thank you for the very interesting post. I have always thought this Chaffing and Winnowing technique is very neat :-)

A few years ago I wrote a class project using this, for a "Security and Cryptography" class. I had never thought about it again until I saw your post today, but here it is, complete with code, documentation and the report that accompanied it. If you look at it, please be kind with both my code and my prose: they were written a few years ago, under a looming deadline and probably with very little sleep :-) But I even implemented a client-server version of the thing...
