drmdecrypt is a tool to decrypt PVR recordings from Samsung TVs into standard transport stream format. There are multiple similar versions out there based on code from SamyGO and various people but they are all either slow, Windows specific, full of bugs or even all together.
This version is fast, POSIX compliant (Linux, FreeBSD, Windows (MinGW)) and is focused on a small number of useful features.
Usage: drmdecrypt [-dqvx][-k keyfile][-o outdir] infile.srf ... Options: -d Show debugging output -k keyfile Use custom key file instead of mdb -o outdir Output directory -q Be quiet. Only error output. -v Version information -x Disable AES-NI support
of for MinGW (Windows)
Samsung has changed the encryption of the PVR recordings a few times so here is a small overview of what the situation is right now. Situation might change over time.
|E (2012)||key file required (needs root)|
|F (2013)||key file required (needs root)|
|H (2014)||key file required (needs root)|
Samsung has moved the decryption keys into the internal storage of the TV. That makes the process more complicated:
1) get root and ssh on your TV 2) ssh to the box and run PVRdumpkeys.sh to generate .key files from the internal storage 3) unplug the USB disk and plug on a laptop 4) run drmdecrypt on it with -k to decrypt the recording
or you can also use SamyGO NoDRM. See: https://forum.samygo.tv/viewtopic.php?t=8105
