Application Registration

[John Smith]

C# DotNet 1.1
I have nearly finished a new application and we want to protect our
investment.

We have purchased the commercial Dotfuscator and have learnt how to use it.

What is the best way to implement product registration? Is there an example
around?

I have read that some people are using the HD Volume number as a key to
ensure each installation is unique. Is this a good idea?

We want registration to be such that the software generates a key (unknown
to the user) and together with the serial number entered is used by our
server to provide a license key.

I would appreciate pointers on a satisfactory solution.

Thank you

Hi there,

This article explains one of the better methods Xml Digital Signatures, its a good place to start if you want to protect your code investment

The really good thing about this is that once you have encrypted the license file, if anyone has a go at it and stuffs it up your application will know about it. Its an introduction but should cover most of the basics
