Babel Licensing

Licensing system for .NET Framework applications and components

Licensing for .NET Application and Components

Babel Licensing is licensing system that allows to license .NET Framework applications and components. It uses asymmetric cryptographic algorithms which means that is not possible to reverse engineer license keys to make a key generator. Furthermore, it integrates with Babel Obfuscator to provide top obfuscation and protection features.

General Features

Completely managed solution to build licenses for .NET applications and components

Works with any .NET technology from .NET Framework to latest .NET Core releases

It integrates seamslessy with MSbuild and includes command line tools to support any build environment

Can run on Windows, Linux and OSX thrugh the NuGet package tool

It perfectly matches with Babel Obfuscator to provide best in class security for any application running on .NET

Licensing Database

Babel Licensing includes a database realized to handle software licenses. This will allow you to store your license keys and make beautiful reports to monitor the performance of your sales. You can also acces the database through an Entity Framework based component, to relize custom solutions suited to the most varied needs.

Babel Licensing

Custom Reporting

Custom Reporting

The license database includes numerous reports to display sales, orders and license usage. Custom reports can be added to display data in different types of charts, pivot grids and map controls. 

Entity Framework .NET Core

Based On Entity Framework

The Babel Licensing database is based on latest Entity Framework technology and includes a .NET component that can be used by external applications to create customized solutions.

How It Works

Babel Licensing can be easily integrated into your application with few lines of code. Just reference the Babel.Licensing package in your application and see how it easy to create and validate a license.

Install-Package Babel.Licensing -Version 2.8.1
dotnet add package Babel.Licensing –version 2.8.1

<PackageReference Include=”Babel.Licensing” Version=”2.8.1″ />

Our licensing library will take care to find the license, verify that the license has not been tampered with and that all the usage restrictions are met.

Create License

RSASignature rsa = new RSASignature();
rsa.CreateKeyPair();

string license = new XmlLicense()
              .ForAssembly(typeof(Program).Assembly)
              .LicensedTo("ACME", "devs@acme.com")
              .WithTrialDays(30)
              .SignWith(rsa).ToReadableString();

Validate License

try
{
    XmlLicenseManager manager = new XmlLicenseManager();
    var lic = manager.Validate(license, typeof(Program));

    if (lic.IsTrial)
    {
        var trial = lic.Restrictions.OfType().First();
        Console.WriteLine("Trial time left: {0}", trial.TimeLeft);
    }
}
catch (Exception ex)
{
    Console.WriteLine("License not valid: {0}", ex.Message);
}
