[App] srf decrypt for HKMFK/JZM

Command line tool to convert a .srf file to decrypted .ts file. I only tested it on HKMFK so no idea if it works on other firmware types.
Install:
- copy srf_decrypt from the zip to the tv (i.e. $SYSROOT/usr/bin)
- add exec attribute if necessary (chmod 755 $SYSROOT/usr/bin/srf_decrypt)
Usage:
Code: Select all
# srf_decrypt <full_path_to_srf_file>
ex: srf_decrypt /opt/storage/usb/sda2/CONTENTS/19700101022506.srf
- a new .ts file will be created in the same directory containing the .srf file. Make sure enough free space is available.
Change log:- v0.1 - First release
- v0.2 - Fixed support for files larger than 2Gb

At first I thought "but!? we already have got drmdecrypt and ffmpeg?! Yet another faster one?"... You should have told that one doesn't need prior key
I confirm works as well on T-JZM.
Btw, SYSROOT is full exec (at least released one), no need for chmod

Yes, on K there is no key dumper so I wasn't able to make drmdecrypt nor ffmpeg work here.
Thanks for testing on T-JZM.

Actually there is a keydumper, read carefully at the end of root procedure, you just have to take it from J sysroot.
At least your stuff is not copyrighted, will include. Thanks for sharing it

tzpvrdmpkeys from J doesn't work here
I though that's why it wasn't included on K
Code: Select all
localhost~ # tzpvrdmpkeys

First news to me, not easy to be aware when nobody reports nothing (works on JZM). One more good reason to include in next sysroot version

I've just added optional destination filename for srf_decrypt to be compliant with srf2ts.sh ts naming.
K sysroot now updated and including it
(cf. changelog)

Great! I like the srf2ts.sh ts naming way more than the default "timestamp" srf names
