Support of DES instead of just CSA

[bsg75]

I have heard that some Power*U provides use DES for encryption instead of CSA. Are there any plans to support DES in vdr-plugin-dvbapi?

AFAICT encryption is forced by DVB standard - and it is the CSA. Please provide more technical details.

Does it really matter, what the DVB standard says, if their are DVB compliant muxes out there that actually don't use CSA but DES?

[manio]

@newspaperman It doesn't matter and has to be supported if it is supported in OSCam. I didn't tell that it will be not supported because it is not a DVB standard. In fact it has to be some kind of standard if it is currently broadcasted by some providers/channels. ATM I don't have a possibilities and time to write this implementation.

Can somebody confirm that this DES encryption is now supported in any Linux DVB software, like tvheadend, mumudvb? I am not asking about OpenEnigma, which is supported for some time in the OSCam and it's depending on hardware/driver and OE version.

tvheadend seems to have AES and DES support. See: https://github.com/tvheadend/tvheadend/blob/master/src/descrambler/tvhcsa.c and https://github.com/tvheadend/tvheadend/blob/master/src/descrambler.h

@bsg75 I am aware of this code, but is somebody using it? Is it working with the OSCam AES/DES support? I think it is only for a SAT/IP devices, which are connected with tvheadend.

In tvheadend powervu channels works with oscam only in stream mode. Support for extended CW API at tvheadend in todo list: https://tvheadend.org/issues/3360
