I have in mind to write up some simple exercies using the Vietnam era US Special Forces subsitution code process.

This code is as insecure and secure as the security of the seeding key. In more advanced use it is rather secure by most standards.

Would require a download of the table (I actually prefer using a "Diana Wheel" over a table), some seed keys, and worksheets,

Any interest?
