Interesting ... I think Paul is challenging the hacker community to crack the key provided for use to a scanner with a serial number. If that is the reason he posted then he must know that the information or conversion is encrypted so that it cannot be reverse deciphered so it must use a high level of encryption.
Just as a side not you cannot decompile to a compilable form the sentinnel software either.
Everyone who buys a key gets a key as well as knowing their own ESN/checksum, which is what is used to make the key. If a hacker wants to try to reverse engineer it, all they need to do is buy their own key.
Now all you need to do is figure out the ESN of the scanner that belongs to, sneak up on the owner and hit them over the head, then take the scanner and you'll have DMR for free!

A hacker can also try every combination from 000000-00000000-000000-0000 to FFFFFF-FFFFFFFF-FFFFFF-FFFF. It may take some time. Thousands or millions of years perhaps.
