Easy to use software licensing system

As promised, the beta version for SimpleLicensingSystem, aka SLS, is now available in beta. This first version is designed for .NET application, and will let you setup the licensing of your app in no time:

  • – Add SLSLib.dll as a reference of your project
  • – Create a instance of a TWLicense, with your product name and a private ID
  • – Test the presence of a license with methods such as IsTrial or IsExpired
  • – Allow your users to enter a license key to enable their license

A tool (SLSKeyGen) is included to generate your license keys.

A sample (in C#) is also included in the package. As you can see, it’s a less-than-10-lines piece of code.

More functions will come soon, such as a C++ API, a more optimized license format, and the possibility to use the license as a container for variables & files. Please contact me if you need more info about the project.

About the security:

The main goal of this project is to provide a very straightforward API. The license and the keys are heavily encoded, and shouldn’t be easy to crack, however the API itself is based on .net, and even it was obfuscated, it could still be reverse-engineered. On the other hand, it’ll do the job to protect your app from what a standard user can do. If someone skilled enough decides to crack your app, he will probably succeed, even if you spent big bucks in the security. That doesn’t mean I won’t improve the tool: the next version will be based on native code, with a lot more of security locks/checks. However, the main objective of this project will remain the ease of use.

Many news!

Hi everyone!

It’s been a while since I didn’t post anything on my blog. As a result, there are plenty of news I’d like to share.

First of all, I fathered my first kid a little more than a month ago. (Which mainly explains why I was so silent on this blog). The name is Akio, and both the mom and the baby are healthy. We’re now both discovering the real value of sleeping…

Celine Piat, from LivingColors took many superb photos of the baby. If you need a professional¬†photographer to take pictures of your wedding/baby/family, I couldn’t recommend you more to check her website.

It’s not the only good news: I also registered Teapot-Hosting as a company. There is sting many things to do, and things don’t go as fast as I wanted, but the business is on its rail. The website was reshaped, business cards were printed, and every user of the service seem to be happy.

As for Teapot, while the hosting is still the main activity, I also planned to release the tools I designed to help me to handle the business. Namely EasyBiz, a piece of software to handle customers/invoices/transactions with many cool features (graphical dashboard, customizable API, reports, plugins…). SLS, The licensing API and the keygen I use to deliver license keys for the Gametools Suite will also be released soon.

I’ll post here as soon as the betas are available.
