iougen is a python module/cli script that can be ran to generate IOU licensekeys.

IOU stands for IOS on Unix and is a full IOS environment that can run as aUnix process. IOU requires a valid key to operate and that is where thismodule comes in.

The code used for generating the license code came from a user who goes byKel. Kel ported the code in 2011 from an original C program written in 2006.I just cleaned it up and made it a package that could be imported for use inother projects (like a web front end)
