    Hello! I have to produce a software license number from a PDA's device ID. Whenever a user submits this ID to web site, the new licence number must be produced according to submitted id and then whenever user uses the new license number in the software, the code should resolve the new id according to PDA's device id and confirms it. For example: The following is a PDA's device ID (7AAF5100226808010d19-c37ad75c0345) and the new license number should be likely this (5FC6-88J9-1264-76K8) How can I produce such algorithm. Is there a code sample? I need a road map to realize the concept. Thank You.

    What a curious mind needs to discover knowledge is noting else than a pin-hole.

      Use simple hashes based using secret company and product hashes as salts and then combine them all to generate a license hash.

        How about Reversing the produced license key and finding the product of the secret company. Hascode only produces numeric numbers. :)

          Yes but you could then tweak the generated hash to ensure that the generate key is within the ascii printable charachter set.....
