Licensecc

Copy protection, licensing library and license generator for Mac and Linux.

Protect the software you develop from unauthorized copies, limit the usage in time, to a specific set of machines, or prevent the usage in virtualized environments. It is an open source license manager that helps to keep your software closed. Among other features if it runs on a "real hardware" it can generate a signature of that hardware and report if the signature doesn't match.

License

The project is donated to the community. It comes with freedom of use for everyone, and it always will be. It has a BSD 3 clauses licensing schema, that allows free modification and use in commercial software.

Project Structure

The software is made by 4 main sub-components:

• a C++ library with a nice C api, licensecc with minimal (or no) external dependencies (the part you have to integrate in your software) that is the project you're currently in.
• a license debugger lcc-inspector to be sent to the final customer when there are licensing problems or for calculating the pc hash before issuing the license.
• a license generator (github project lcc-license-generator) lccgen for customizing the library and generate the licenses.
• Usage examples to simplify the integration in your project.

How to build

1. Check out the repository including the submodules:

git clone --recursive https://github.com/tulrich2/licensecc.git

2. From within the repository root directory, configure the CMake project:

cmake -S . -B build

You can also specify the name of the software you want to generate and validate licenses for:

cmake -S . -B build -DLCC_PROJECT_NAME=<software_name>

3. Build the license generator and the C++ library

cmake --build build --target environment lccgen licensecc_static -- -j <num_threads>
