How does a key generator work?

keep your fingers crossed for this thread !
i hope it isnt locked
coming back ..
taking in simple language ..
the software (shareware) checks the keys for certain traits
say, its digit total or total of 1st,3rd,5th.. digits or some CRC or decrypted data, etc
it checks if the key confirms to those standards programmed in the software.
usually softwares encrypt your "email addr" or some "activation code" they give you or sometimes a combination of both into the key ..
and when you enter the key, it checks if the data still corresponds to wht you've earlier entered !
our friendly hackers study the software using various tools to understand which parameters are being checked by the software to validate the key.
once you have that info ... even you can create a keygen.
how to do this ... is something not worth discussing (atleast here
)
btw, just for info ... i have no idea how to crack a soft

Keygens are developed by crackers who crack the target software's code by reverse-engineering to find the algorithm that does the key verification.
Once the algorithm is known, the crackers write their own program that runs this algorithm in "reverse" (not literally, ofcourse ) to generate valid codes.
This algorithm may be changed in the next version of the target software so this explains why u may need another keygen for this version.
Edit: alib_i, I 'ppose we posted together.

It means examining someone else's product to see how it works and why it's designed in that particular way.~Phenom~ said:
These days, many computer enthusiasts seem to think the term applies only to computer products, and mainly to software at that. But the term was coined long before computers came into general use and was/is applied to all branches of technology.
The purpose of reverse engineering may be
- to crack a code
- to make a counterfeit product
- to study a competitor's product
- to analyse its good and bad points
- to repair a damaged product when the manufacturer's manual is not available
and so on.
