I recall a tool from the early 1970s that could take a program and change all of the variables to combinations of "I", "O", "0", and "1".
The "real source code" was kept on punched cards in a vault, and the "encrypted source code" was kept online. It was believed that a thief would find the "encrypted source code" to be useless. I don't know if that belief was ever put to the test. John P.
