DCW = C6F316F23EA43D752511 00 [77FEDED1BC61E81F} <- ist das vorletzte DCW oder ECW ?
With 000x 01 02 03 is indicated as Aes_Box_Key. I think something similar on astro if I'm not mistaken from a long time ago with dimeno_magic mod.
Yes I agree with you, the K1 used for CW must be 2x8, when I say 8+8 I mean the same thing.
In short 2 equal octets, otherwise it couldn't be reduced to DES, obvious.

These bytes indicate the use of 3DES, otherwise with 0010 AES.54 14 00 02 00 01 xx xx xx xx xx xx xx xx xx xx xx xx xx xx 00 01
This is very strange, I was not aware of this. This byte should indicate the algorithm to be used in generic mode, 02 is 3DES, 10 aes, 01 aes_box_key, 00 no algo selected? I don't know.i make log card-stb with saleae logic analyzer ,and see change on last 10 bytes on ins7e
before: 00010202030002020203
now: 00010002030000000000
Then it could also be like V13, everything indicates 3des, but in the end it's a des, without a brute you can't know.
