|
|
*
|
|
* For more information read the code and the comments. We have tried to
|
|
* write clear code with lots of comments so it is easy for others to
|
|
* understand what is going on. There are some things marked *FIXME*,
|
|
* that are mostly unknown or not fully understand.
|
|
*
|
|
* WHAT WAS TESTED AND WAS WORKING:
|
|
* - Cards with bulcrypt v1 ("cherga"/carpet) are working (we have cards
|
|
* that report CardType: 0x4c and 0x75.
|
|
* - Cards return valid code words for subscribed channels.
|
|
* - Tested with channels encrypted with CAID 0x5581 and 0x4aee on
|
|
* Hellas 39E. Both MPEG2 (SD) and H.264 (SD and HD) channels were
|
|
* decrypted.
|
|
* - Brand new cards were inited without ever being put into providers STBs.
|
|
* as long the protocol you are using is sending EMMs to the card.
|
|
* - AU was working (subscription dates and packages were updated)
|
|
* as long the protocol you are using is sending EMMs to the card.
|
|
*
|
|
* WHAT WE DON'T KNOW (YET!):
|
|
* - How to deobfuscate v2 codewords.
|
|
*
|
|
* PERSONAL MESSAGES:
|
|
* - Many thanks to ilian_71 @ satfriends forum for the protocol info.
|
|
* - Shouts to yuriks for oscam-ymod, pity it is violating the GPL.
