Open License Manager

A license manager written in C/C++ for Windows and Linux environments.

It allows to 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 License Manager that helps to keep your software closed ;-)

The software is made by 2 main sub-components:

• a C library with no (or minimal) external dependencies (the part you have to integrate in your software).
• a license generator written in C++ (allows you to generate a license).

these modules are planned....

• a license backoffice in php (in order to handle multiple licenses).
• a license debugger to be sent to the final customer when there are licensing problems.
• a log descriptor in order to decrypt logs generated by the license system.

You can notice 2 more sub-projects:

• bootstrap: allows to generate private keys and modify the library on the fly after the downloading.
• testing : runs the tests (and publish the results on cdash)

Licensing

The project comes out with a very large freedom of use for everyone (and it will always be). It uses a BSD 3 clauses licensing schema.

How to build

prerequisites

GCC (Linux), MINGW or MSVC (Windows) cmake, boost, openssl (Linux/MINGW), you can find detailed instruction for each supported environment in the wiki. Below an overview of the basic build procedure:

git clone https://github.com/open-license-manager/open-license-manager.git
cd open-license-manager/
mkdir build
cd build

on Linux

cmake .. -DCMAKE_INSTALL_PREFIX=../install
make
make install

on Windows (with MSVC 2015)

Boost:
Download latest boost sources from https://www.boost.org/
Run: bootstrap.bat
Run: b2 runtime-link=static
Set boost path in CMakeLists.txt BOOST_ROOT

cmake .. -G "Visual Studio 14 2015 Win64" -DCMAKE_INSTALL_PREFIX=../install
cmake --build . --target install --config Release

cross compile with MINGW on Linux
