drmdecrypt is a tool to decrypt PVR recordings from Samsung TVsinto standard transport stream format. There are multiple similarversions out there based on code from SamyGO and various peoplebut they are all either slow, Windows specific, full of bugs oreven all together.

This version is fast, POSIX compliant (Linux, FreeBSD, OSX,Windows (MinGW)) and is focused on a small number of usefulfeatures.

Features

  • Reading title and channel from .inf file
  • Bulk decoding multiple files
  • AES-NI support (5x faster) (x86_64 only)

Usage

Building

of for MinGW (Windows)

Support status

Samsung has changed the encryption of the PVR recordings a fewtimes so here is a small overview of what the situation is rightnow. Situation might change over time.

Cracker
Model yearStatus
C (2010)supported
D (2011)supported
E (2012)key file required (needs root)
F (2013)key file required (needs root)
H (2014)key file required (needs root)
J (2015)unknown
K (2016)unknown
M (2017)unknown

Notes for Models E and later

Samsung has moved the decryption keys into the internal storage ofthe 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
