Hello Guys,

I am developing an application in vb.net. Now my employer asks me to develop a feature that "We have to provide an activation code to the End user to activate the product, for this we will take System ID and serial number from customer".

Here
System ID means: In this application I have to generate a unique id by using Sl no. of Motherboard or HDD or etc. (yet to decide).
Serial Number: We will provide a serial number with the product
Activation Code : By Using the above I have to generate an activation key (of 32 chars)

after product activated, s/w will work in only in that system.
the same activation code will have not to work in another system.

I am in situation that i don't know where to start this process.

Any Ideas are welcome.

Thanks in Advance

Don't bother too much about this unless you know for a fact you can obfuscate or Sign your project.

Do yourself a favour and download ILSpy. Then in ILSpy open your assembly..... yeah I know, it is devastating.

However all is not lost. Have a look at this post, maybe it has some value to you.
