Hi,

does anybody know a good jumpstart for techniques to protect software with
license keys?

Thanks in advance

Here is the text I replied in the German VB.NET group:

Du sagst leider nicht, um welche Form der Lizenzierung es sich handelt.
Eventuell reichen die .NET-eigenen Lizenzierungsmechanismen aus:

..NET Framework Developer's Guide -- Licensing Components and Controls
<URL:http://msdn.microsoft.com/library/en-us/cpguide/html/cpconlicensingcomponentscontrols.asp>

..NET Licensing

Sonst ggf. kommerzielle Komponenten:

Well the price is right - but my main concern as a developer would be
the fact that it does not appear to come with source code. Since they
are not providing support you have no way of resolving any problems
that might occur. The lack of source also means that you are going to
have to distribute their DLL - this makes your licensing mechanism very
obvious to any would be crackers and means that you can't obfuscate the
calls to the licensing code.

Our licensing system comes with source for the licensing library which
means it can be fully integrated into your application or component and
fully obfuscated. I think $80 is a reasonable price to pay to ensure
you have adequate support for what is a fairly critical part of your
application or component.
