Hi,

once again (hopefully the last time):

The piece of software, H.Berlioz presented on his page does not deal IN ANY 
WAY with software decryption of SECA encrypted channels !!! It deals with the 
transport of ECM/EMM messages to a smartcard. The decryption of the keys 
(delivered by the ECM/EMM stream) is done by the SMARTCARD, the decryption of 
the DVB stream itself is intended to be performed by the DVB descrambler, 
built-in to the TI chip on the DVB card. All of this is perfectly legal and 
the way it has to be done anyway !!!
The only thing this code could be useful, is the control of smart-card 
readers, which are not (or cannot be) directly attached to the DVB card.
BTW the whole software is useless (for other things than learning), as there 
are no API calls in the DVB driver to support direct control of the 
descrambler.
I hope this clarifies things a bit.

Regards,

Rolf
