I have a problem to identify whether a software (an application) comes from legal version or pirated version (crack)?

Please help me out. I would appreciate for any suggestion.

Thanks.

The only means of knowing would be to check with the customer care unit of the company whose product your buying. Usually they will check the key you have to ascertain its validity.

Apart from that it would be hard to know especially when the software was well cracked. The company alone would have the means to check their records.

  • Actually i wanna check the software whether they are genuine or not. could we know using some information from properties of the software (right click at the software and choose properties)? From the details and digital signatures. if it has copyright at the details and has digital signatures, could we conclude that the software is genuine? – Deni Yulianti Dec 3 '16 at 13:06
  • @Deni that answer is not that possible as software method for checking authenticity differs per vendor. The best check is the key. It can be done from the app itself or y checking with the vendor. Some apps will connect with the official site to check, others will not. So there is no standard means to do so. The key has the copyright and digital signature information stored there and the vendors are the ones that can decrypt it to determine if your copy is genuine. You the user won't be able to do that. – George Udosen Dec 3 '16 at 13:18
  • if so, how to do the software audit to determine genuine or not? please help me out. – Deni Yulianti Dec 3 '16 at 13:25
  • Are you a vendor or checking use of authenticated software for perhaps your firm? – George Udosen Dec 3 '16 at 13:29

    Even free software has genuine license, always download from source or authenticated/approved resellers or distributors. – George Udosen Dec 3 '16 at 15:12

You could try computing a hash of the application and it's related library files against either the published hash (if available) from the vendor, or if you have a legit copy of the program in question, create your own hash. The easiest way to create a has in Windows is get-FileHash.

If the hashes are different, then the program / files have been modified.
