Eudoxys Sciences releases mguid developer tool to create and manage magic GUIDs.

A magic GUID is a GUID that embeds an encoding related to the source of the GUID. Magic GUIDs can be used to determine whether two GUIDs were generated in the same context. That can be useful for applications that need to check whether a GUID is exogenous, i.e., was the GUID created by another application. It can also be used by a third application to determine whether two GUIDs were generated by two different applications or by the same application.

Magic GUIDs contain a pattern that is uniquely identifiable if the magic number is known. The --random option generates a Version 4 GUID using a random magic number. If you know the magic number you can verify that a GUID was generated with the magic number by using the --check option. If an app has two GUIDs, they can verify that they were generated using the same magic number using the --same option.

The mguid module can also be called from another Python module using the main() function or from the command line of a shell. The command line options are also available as python functions in the module.

For more information on the mguid tool, see the mguid documentation page or download it from the mguid repository on github.
