cracking .Net Program

Koyuta (and any others who are interested in .NET reversing),

In preparation for writing a tutorial on .NET reversing, I went ahead and wrote a keygen for FarPoint Spread for Windows Forms v1.0.2.0. In the spirit of things, I wrote the keygen itself in .NET (C#). Basically, the tutorial I will write will describe step-by-step from the beginning how I reversed the algo, wrote the keygen, and what was involved in doing so.

A few notes:

First, I reversed the serial check in the installer, not the serial check in the application itself. The dll containing the serial check for the installer is written in .NET (Managed C++), so I figured this could also act as a tutorial for reversing installer serial checks (which Koyuta seemed to be interested in). Obviously, the installer and application use the same validation algo, just in different files and different environments (and also different languages in this case; the installer is written in Managed C++, the app itself appears to be C#). So, the keygen itself is no different for having done this, but just a heads up that the tutorial will involve reversing the installer (which is still .NET), not the app itself.

Second, I have included the source code for the keygen in my release, which may be of some interest to those who are planning to read the tutorial, or those who are interested in just seeing some interesting C# code.

Third, in addition to generating valid Product Key/Serial Number combinations, the keygen also includes the ability to validate/verify any PK/SN you type in. The purpose of this is to save you some trouble when following along in the tutorial, so that as you write your own keygen (which you should do, else what is the purpose of the tutorial!), you can see if its output is valid quickly without testing over and over in the installer (which is very very slow to validate the PK/SN for some reason). Or, if you don't want to use my keygen to do the validation, you can just take the included source and implement the validation in your own keygen/app.

I have uploaded the keygen, keygen source, and install files to the exetools FTP (/incoming/FarPoint Spread for Windows Forms v1.0.2.0 with Keygen). I only uploaded the install files to ensure that the version I wrote the keygen for and will write the tutorial for (1.0.2.0) will be immediately available to everyone, even if a newer version is out (thus making 1.0.2.0 hard to find).

Koyuta, please send me a PM or something to let me know if you are still interested in having this tutorial. If you're not interested, I'm not sure if I will still make the tutorial (you're the only one who really seems interested in .NET), because it will be an extremely time-consuming process.
