How Is The Product Key Generated?

Recommended Posts

Guys I would like to know how is the product key generated through a part number of the CD. Whats the software these people use to generate a CD key in order to use any software. Can we common people use that software and if yes then how?

The product key generation is different for different applications. The trick lies in making an algorithm, which can decrypt itself to unlock the software - and can be designed in any programming language :)

There could be fixed product keys - generated by an algorithm based on fixed paramaters like windows version etc... (Eg. MS Windows Serial keys).

or there could be varying keys generated based on variables like a name - eg. winzip... and yet others which use some constant like machine processor id number as a constant and a name / email address as a variant...

So if you wanna learn the art of decrypting the algos... you gotta spend a lot of time understanding API's and some old friendly tools like w32dasm and Numega's killer Softice ... :D

Most importantly you have to learn Assembly language.

If u are packaging and distibuting u'r software using 3rd party installation softwares like Installishiled,Wise installation, Flex

They provide u option to generate standard set of CD keys or product keys to unlock the software.

They also provide u the option of making the software run as trial version for the number of days set by u.

comments in above posts helps u if u wants to unlock them :)

There must be a link or website or something where it can be shown so that we can understand it properly how to generate a product key

I did not understand, Do u just want to know the methods/algorithms generally used to generate Product keys, or do u want to know about the process of generating the keys using the above softwares.

DISCLAIMER :

This post is for educational purposes only. I would personally urge users to buy a software if they plan to use it beyond the legally allowed trial period.

@chandanasta : Since the procedures for serial key generation varies greatly, it would be best to check out some standard application cracking procedures like :
