23 * For more information read the code and the comments. We have tried to
24 * write clear code with lots of comments so it is easy for others to
25 * understand what is going on. There are some things marked *FIXME*,
26 * that are mostly unknown or not fully understand.
27 *
28 * WHAT WAS TESTED AND WAS WORKING:
29 * - Cards with bulcrypt v1 ("cherga"/carpet) are working (we have cards
30 * that report CardType: 0x4c and 0x75.
31 * - Cards return valid code words for subscribed channels.
32 * - Tested with channels encrypted with CAID 0x5581 and 0x4aee on
33 * Hellas 39E. Both MPEG2 (SD) and H.264 (SD and HD) channels were
34 * decrypted.
35 * - Brand new cards were inited without ever being put into providers STBs.
36 * as long the protocol you are using is sending EMMs to the card.
37 * - AU was working (subscription dates and packages were updated)
38 * as long the protocol you are using is sending EMMs to the card.
39 *
40 * WHAT WE DON'T KNOW (YET!):
41 * - How to deobfuscate v2 codewords.
42 *
43 * PERSONAL MESSAGES:
44 * - Many thanks to ilian_71 @ satfriends forum for the protocol info.
45 * - Shouts to yuriks for oscam-ymod, pity it is violating the GPL.
