NDS CW is crypted, trying to decrypt unique pairing mode 0x8B (CAID 0987)

too big address space, It will take much more time to find than you alive.
 
Because:

DES -> 56 bit -> few days
3DES -> 112 bit -> few days x 2^56 = a few trillion days

There are so much more possibilities that a bruteforce is not feasable with current hardware.
 
Try it this way.
ins7E "0000000000010202030000000000" (6E736B202F47AC57XXXXXXXX0000000000010202030000000000 )
And show Tag55_01 =???

I don't know what you are all trying...
It does not matter which mode the card is in (All those mode numbers we don't know what they mean only Cisco knows), as long as you get an ECW.
In the last payload (x88) there is no ECW, in the other (x8B) there is one.

If you have an ECW, the question is how is this ECW encrypted.
If 3DES (or AES or whatever not bruteforceable standard anno 2020) -> no possibilities
If DES -> Possible, if you are able to get a DCW somewhere from (you could also bruteforce it for a given stream, especially if 48 bit CWs are used, for 64bit CWs it's hard)

But my guess is: it's 3DES so just give up.
If you are able to get a DCW somehow try tro bruteforce the ECW/DCW...if not it's very likely 3DES.

We write all about german providers here and not about indian. Nobody here from germany
a) knows your provider
b) can give you dcw
c) can give you your unqiue key

Zum Vergrößern anklicken....
@Ghafar : You've already gotten the correct answer. There is no way possible to bruteforce or calculate your unique Key.
