-_2" And THEN go ahead and decrypt the file? Because from what i understood the first line of byterange is what is causing the video to not decrypt. By the way, by any chance did you successfully get an HD video to decrypt?

Each segment specified by byte range needs to be decrypted separately. Each segment has it's own IV.

So if the first byte range starts at 6772528, then everything before it needs to be removed.

Yes I've decrypted HD content.

oh. Okay! sorry its taking me a bit to understand.
there is many byteranges. is the only way to do it, one at a time?
and youre using a PHP script, right?

Yes. They have to be decrypted distinctly.

No, mine is written in Python. I never did use UVD. I have my own tweak that goes into the netflix app and extracts the M3U8 playlist and keys. It also runs a service on the ipad that let's me trigger playback of a movie and then after it captures the playlists and keys, it stops playback. I can bulk rip that way.

But, everything else is the same as what you are doing. The python code downloads the media, decrypts it, and so forth.

it seems as if your method is much more efficient. do you mind if i can try it out? because im fairly new to php and that might be why its so complicated for me to get this right. & thanks again for sticking around & helping me. i was never able to even know where to begin decrypting hd files until now.

same here, i feel like we are getting closer to being able to decrypt these HD files. Especially With The Help Of enrud. We should have this in no time!

OK, I wrote a python script that does what you were trying to do in php. It requires that you have already downloaded the files from the cdn. I tested it against your shrek sample. It will also work against HD stuff as well.

This runs in Python 2.7 and requires either the pycrypto or M2Crypto packages which implement AES. This *should* work platform independently, but I haven't tested that.

Have fun.

thank you! question, every time i try running the script, i get this in response. did i miss a step?

"I:\Python27>python decrypt.py
Traceback (most recent call last):
File "decrypt.py", line 19, in <module>
except ImportException:
NameError: name 'ImportException' is not defined

I:\Python27>"

Sorry. But it does mean that you need to install a crypto package for python. Either of these will work:
https://pypi.python.org/pypi/pycrypto
https://pypi.python.org/pypi/M2Crypto

Fix attached.
