Hi. I'm awared that the code keys is rolling frequently from time to time. But I badly wants to know a bit more about code keys if the 16 digits with 8 bytes code numbers are static for reasonable long period, say about few months stationary, AND most importantly, is the satellite channel Providers' Ident code number are static ???? That normally comes from CAS's Irdeto/Betacrypt, Seca, Nagravision, Cryptoworks and Viaccess. Also, is the two-digits keys '01', '00', '21' and or even '22' are static ?? Well, at the other hand of other CAS named BISS - Is the BISS code number are static ?? Your reply with explanation would be greater appreciatedly.
