Validation of product key

Feb 4, 2010 at 3:10 PM

can we validate key that is generated by key generator ? or can we encrypt some information in that product key ?

What do you mean by "encrypt some information in that product key?"


Also, when you say "can we validate key that is generated by key generator?", are you asking if there is a way of making sure that the product keys that are generated will work for sure?

If you want a suggestion for validating a generated product key, try this download:

If you want to automatically validate all the product keys as they are generated with Product Key Generator, use it as an example to modify the code for the Generator to validate each key after it is generated.


Sorry for the delay!

i dont have much (or any) experience with, but it would be possible to simply modify product key generator to create only unique product keys. 

Depending on the number of characters in the product key, the probability of creating just 2 identical product keys would be highly unlikely. (For example: if you have a product key that is made up of 15 letters and since there are 26 letters in the alphabet, there are 1,677,259,342,285,725,925,376 possible unique product keys that could be generated.

However, you could check to make sure that a generated product key has not been created already. This could be accomplished by simply saving each product key in a text file when it is generated. Then, for each product key that is generated, it would be compared to the saved list to make sure it is not already in the saved file. If it is already in the saved file, a new product key would need to be generated (since it already exists).
