softcams keys are publicly knows, and dont change very often, monthly? weekly? daily?
an ND$ key changes on average every 9 seconds, twice, it uses 2 key lines, one in use, and the next one, then it swaps, so by the time you found the key, created a softcam file, loaded it onto your receiver, and restarted the cam for the new softcam to kick in, the key needed to clear the picture would have actually changed 4 or 5 times
