evoleap-licensing

Introduction

elm is a web-based licensing system with a simple, full-featured JSON API for making license enforcement requests. This package is a client API for integrating into your python applications in order to license through elm. This package is based on python version 3.7.

The elm client API for python provides implementations of the elm web API for python-based applications. The API is designed around a single abstraction, called a control manager, that simplifies the steps needed to add licensing to a client application.

The control manager implementation provided in this package is only suitable for desktop programs. It offers functions to:

• Register an instance and user of a product
• Validate that the current instance and user have access to the product
• Manage client-side state, such as registration status and instance and user UUIDs
• Support grace periods that allow users to access the product while offline
• Detect whether the end-user is modifying the system clock in order to gain unauthorized access to the product

It is up to the ISV to ensure that the state object produced by the control manager is stored using a secure storage method, i.e., stored in an encrypted manner on the end-user's computer. If the end-user is able to manipulate this state, then they can bypass the licensing controls and gain unauthorized access.
