Detailed Description

Motivation

In many applications it is desirable that the user only has limited access to the implemented software functions. A licensing mechanism that manages these access rights is often used for this purpose.

Concept

1. Definition of license data
2. Provide management of license collections
3. License check using (via binding more general interface iauth::IRightsProvider)
4. Low-level license key generation (Encryption)
5. Device persistence of license data.
6. File-based peristence of license data.
7. Diagnostics information about the license status in the application

We define following types of license data:

1. List of all product variants. This includes the overview of all available products and the associated licenses.
2. List of product installations.
3. Encrypted information file containing all license keys for a given product installation.

Each product application has knowledge about all available product licenses and activate them by reading and validating the license keys from the license file containing license keys. The license keys will be defined by Product Manager before shipping of the installation setup to the customer.
