How to decrypt YouTube Movies & TV files

[whs912km]

Youtube isn't quite as simple as that. There's additional json data being sent with the license request, and a ton of various headers. A custom script is needed.

These are the keys I got for the sample url:

f5fe916b23c458dc9583329308759f7a:bc38c9c391c28bb5eaa41811ddc3b350

how to have found the right pssh ? eme found wrong and short pssh ...

also you can put here ?

Use https://greasyfork.org/en/scripts/373903-eme-logger and https://chrome.google.com/webstore/detail/tampermonkey/dhdgffkkebhmkfjojejmpbldmpobfkfo?hl=en to retrieve it.

[whs912km]

yes, i know that
but tampermonkey can't find real pssh. but only short and wrong pssh
useless to get the key. need to be convert some value, but not idea wich one ...

I think my issue is the license URL. I can DM you the one I'm using, but I think it's wrong and could be why it's providing five keys that don't work. At least two of the five KIDs it gave me match the two that you sent.

I can confirm that the keys you provided decrypts the audio correctly (used mp4decrypt) but not the video (none of the variants: WEBM / VP9, MP4 / VP9, MP4 / AVC1, using Shaka Packager and mp4decrypt).

The license url itself is pretty straightforward: https://www.youtube.com/youtubei/v1/player/get_drm_license?alt=json&key=KEY.

The video key I sent you works for the SD version since that's the max quality I get for that particular movie. Other movies do give me 1080p, and yt-dlp does seem to be able to dig it up here, but max SD in browser for some reason. Kind of weird, but it's just youtube being youtube I guess.

about your post#30 to find lic url simply search "lic"

I had to update my version of the script and console then displayed all available values.

The license url itself is pretty straightforward: https://www.youtube.com/youtubei/v1/player/get_drm_license?alt=json&key=KEY.

The video key I sent you works for the SD version since that's the max quality I get for that particular movie. Other movies do give me 1080p, and yt-dlp does seem to be able to dig it up here, but max SD in browser for some reason. Kind of weird, but it's just youtube being youtube I guess.

That's the license URL I originally used but it doesn't seem to work with GetWVKeys (I passed all request headers and the full alt & key parameters but it gives error 400). I used a different license URL and none of the five key IDs and keys work like yours did. What are you using to retrieve the keys?

Looks like 1080p works on Android but not Chrome on Windows. As you said, it's YouTube being YouTube.

I don't think it's going to work with the Getwvkeys site as is. There's cookie data and encoded json requests that need to be passed, and you'll probably need a custom script for it. Have you checked their discord? I'm pretty sure there have been yt scripts in there that uses their API.

1080p works great normally, even with L3. It's just this movie in particular that doesn't give me anything higher than SD in browser.

Can I ask what methods you're using to get keys? Is it Getwvkeys or a script of some kind? I can't seem to figure out what headers are needed.

[whs912km]

i've get keys with edited script. python script. not trough getwvkeys

and what headers ? no need headers

[besweeet]

I don't think it's going to work with the Getwvkeys site as is. There's cookie data and encoded json requests that need to be passed, and you'll probably need a custom script for it. Have you checked their discord? I'm pretty sure there have been yt scripts in there that uses their API.

1080p works great normally, even with L3. It's just this movie in particular that doesn't give me anything higher than SD in browser.

Good idea to check for a script. Found one for YouTube which was able to properly retrieve keys once I provided the cookie header. Can only decrypt the 480p version which is unfortunate. To me, SD-only videos don't cut it in 2023.

[stabbedbybrick]

Yeah, Youtube is being annoying and will only serve up 1080p on PC for seemingly random titles. Like https://www.youtube.com/watch?v=6lCCk6rgn84 for example, you should be able to get FHD with your script.

yt-dlp can download all resolutions but the keys and shaka-packager don't decrypt them. The GetWVKeys admins said it's because 1080p is L1 which cannot be [easily or publicly] decrypted.

[stabbedbybrick]

Well, that's not true. L3 works perfectly fine:

Hmm... What could I be doing wrong? I take the same keys I use for the 480p WEBM DL (which works) but for the 1080p WEBM and it doesn't work. Are there different keys I need to retrieve?

[stabbedbybrick]

Yes, they are different. Audio is the same, but they differ depending on SD or HD.

480p:

--key c8a34895e6cf5f829d5fbfa8b17a4db5:1a7981d8ae45e549621e5f4da66de542

1080p:

--key e5add253150450bda1f09f79959a32fd:0db74b99402408a3559d86ded402f0ce

As far as L1 vs L3, it might be different for the paid movies. I haven't checked those. But for these "Free with ads", L3 is enough.

[besweeet]

Then the mystery is how to obtain the 1080p keys as you have...

[CrymanChen]

Guys,

I saw this note when converting the cURL to Python on curlconverter.com

[Attachment 70325 - Click to enlarge]

So when it says json_data will not be serialized by requests exactly as it was in the original request, what should I do? (It is a bit different from those in normal situations)

I used WKS-KEYS to get the content keys, and I modified the original one, uploaded it to GitHub for convenience.
Would anyone have a look at my code, for when I ran the .py program, it said "you should generate a license first"...

URL hidden by user
I have pasted all the things includin' cookies, headers, params and json_data to the headers.py in the WKS-KEYS.
Much appreciated.

Should it be

response = requests.post(
    'https://www.youtube.com/youtubei/v1/player/get_drm_license',
    params=params,
    cookies=cookies,
    headers=headers,
    json=json_data,
)

Or should it be like this:

response = requests.post(
    'https://www.youtube.com/youtubei/v1/player/get_drm_license',
    params=params,
    cookies=cookies,
    headers=headers,
    data=data, 
)

[stabbedbybrick]

Then the mystery is how to obtain the 1080p keys as you have...

If we parse the license request, we can see this:

{'trackType': 'DRM_TRACK_TYPE_HD', 'keyId': '5a3SUxUEUL2h8J95lZoy_Q=='}, 
{'trackType': 'DRM_TRACK_TYPE_SD', 'keyId': 'yKNIlebPX4KdX7-osXpNtQ=='},
{'trackType': 'DRM_TRACK_TYPE_AUDIO', 'keyId': '-QxhjmVLVyiyATweN8T-Uw=='}

So there is no mystery. If the movie is offering HD, you should be able to get them same way as the others.

@CrymanChen:

You're missing the actual license request. If you look at your curled data, there's a 'licenseRequest' in the json.

[besweeet]

If we parse the license request, we can see this:

{'trackType': 'DRM_TRACK_TYPE_HD', 'keyId': '5a3SUxUEUL2h8J95lZoy_Q=='}, 
{'trackType': 'DRM_TRACK_TYPE_SD', 'keyId': 'yKNIlebPX4KdX7-osXpNtQ=='},
{'trackType': 'DRM_TRACK_TYPE_AUDIO', 'keyId': '-QxhjmVLVyiyATweN8T-Uw=='}

So there is no mystery. If the movie is offering HD, you should be able to get them same way as the others.

I continue to hit a wall...

If I curl the get_drm_license request from my Android phone, it returns all three track types (per your quote above). However, if I submit everything through the GetWVKeys script, it continues to only give me SD and audio.

I looked through the script and found headers and context information. I swapped everything with headers and other data from my phone yet it still only returns SD and audio.

I'm starting to think it's the GetWVKeys Python script I'm using. Maybe it's not passing everything that YouTube needs and it defaults to desktop.

Are you using the YouTube link I sent or a different link? GetWVKeys said that some older HD uploads are L3 while newer ones are L1.

I tried CrymanChen's script and get the same error. I've added full headers to headers.py and added an empty section for params and json_data. I've copied the curled json_data (starting with context all the way to drmVideoFeature (since that is last) but the same error comes through: "generate a license request first!" It's probably a formatting error but I've had over 100 unsuccessful tests today.

[stabbedbybrick]

Yeah, I'm not really sure what's wrong. For these "Free with ads" movies, it's seemingly random what titles have HD on PC. The one you first linked (Super Size), is 480p max. The one I linked later (Pumping Iron), is 1080p. Every movie I try that offer HD can be decrypted with L3, so that does not seem like the limitation. Unless there's an unreal coincidence that I'm picking only titles that work, it's Youtube itself that's limiting what is available on PC. I'm sure it's possible to write a script that emulates an android device request in order to get all titles in HD, but these movies are so easily accessible elsewhere, I can't imagine someone has gone through the trouble of doing that.

You can try this:

1. Pick a movie that you know have 1080p in browser and actually select it in the player.
2. Refresh the page, play movie, and then curl the license or export whatever data your scripts need.
3. You should now theoretically get three sets of keys. One for HD, one for SD, and one for Audio.

[CrymanChen]

@CrymanChen:

You're missing the actual license request. If you look at your curled data, there's a 'licenseRequest' in the json.

So may I ask how to modify the script...
Letting the script use the request in the json_data rather than generate a new one?

I tried exactly thar but with no luck. I can DM what I've tried if you're interested in investigating.

If you read through this great post by A_n_g_e_l_a, she talks about generating an extra challenge. That's what you got to do for 'licenseRequest'. And it looks like she's using WKS, just like you, so you might be able to adapt it to youtube with the help of her examples.

I tried exactly thar but with no luck. I can DM what I've tried if you're interested in investigating.

I don't think there's much I can do, unfortunately. You'll have much better luck by asking in their discord.

weird right ? different pssh and still the same keys , do you think youtube only cares about "videoId" ?

If you read through this great post by A_n_g_e_l_a, she talks about generating an extra challenge. That's what you got to do for 'licenseRequest'. And it looks like she's using WKS, just like you, so you might be able to adapt it to youtube with the help of her examples.

This is a great path to follow, but youtube is a special case where you need to make a small change because license in base64 can have unwanted characters .

here is a small hint to fix the problem (thanks to ElCap):

licence.json()["license"].replace("-", "+").replace("_", "/")

or you can simply use a script called "TPD-Keys" and you will have your keys , additionally some downloader applications may get the keys for you (don't know if they would provide keys for HD )

Looks like TPD-Keys requires device_private_key and device_client_id_blob which require root to obtain. I'm out of luck.

No you are not out of luck yet , please take a look at this thread to get your L3 CDM:
https://forum.videohelp.com/threads/408031-Dumping-Your-own-L3-CDM-with-Android-Studio

TPD-Keys requires Widevine RSA key pair file , you can get that from the cdm using the method in this post:

Good Luck

That's a good point. And it would seem that PSSH is irrelevant and the license stays the same for everyone.

Since this forum tend to favor WKS-KEYS, I cobbled together a youtube script for it. I'm more of a "tinkerer" than a programmer, but it seems to work all right. Just drop it in the wks-keys folder, put the curled license data in headers.py and run it.

import requests
import json
from pywidevine.L3.cdm import deviceconfig
from base64 import b64encode
from pywidevine.L3.decrypt.wvdecryptcustom import WvDecrypt
import headers

pssh = "AAAAQXBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAACEiGVlUX01FRElBOjZlMzI4ZWQxYjQ5YmYyMWZI49yVmwY="
lic_url = "https://www.youtube.com/youtubei/v1/player/get_drm_license?alt=json&key=AIzaSyAO_FJ2SlqU8Q4STEHLGCilw_Y9_11qcW8"

def WV_Function(pssh, lic_url, cert_b64=None):
	wvdecrypt = WvDecrypt(init_data_b64=pssh, cert_data_b64=cert_b64, device=deviceconfig.device_android_generic)                   
	raw_request = wvdecrypt.get_challenge()
	json_data=headers.json_data
	json_data["licenseRequest"] = b64encode(raw_request).decode("utf-8")
	widevine_license = requests.post(lic_url, cookies=headers.cookies, headers=headers.headers, json=json_data)
	license_b64 = widevine_license.json()["license"].replace("-", "+").replace("_", "/")
	wvdecrypt.update_license(license_b64)			
	Correct, keyswvdecrypt = wvdecrypt.start_process()
	if Correct:
            return Correct, keyswvdecrypt   
correct, keys = WV_Function(pssh, lic_url)

print()
for key in keys:
    print('--key ' + key)

Really appreciate it. Finally made it by trying on my own.

However, may I ask which is the manifest...
