Helix GO / Videotron

First of all, I've been lurking for around 2 weeks and need to say the amount of resources available to the public and the knowledge that some users are willing to share is amazing. 2 weeks ago I had no idea what was DRM and MPDs and stuff. Now I'm pulling WV keys from those files.

Or at least I try. Been having issues with Helix / Videotron.

Was able to get PSSH from different python scripts, not all of them would give me the right one (length)

PSSH: AAAAW3Bzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAADsSJDRhMWQyOWJmLWYyMzgtYjZjZC1iYmUyLTVhZTQyMzM4MTExMyITNTkyNzkyMzU3NTA5OTgyMjE2Mw==

KID: 4a1d29bff238b6cdbbe25ae423381113

Now to get the key, I tried everything I could find and I just cannot find it. Websites/APIs/scripts don't find it, I played with headers and all that and no go.

I don't want the key per se; I want to know HOW you managed to get it. I already have the key some guy pulled it for me. cb10xxxxxxxxxxxx6b51
All he needed was a CURL to Python from the license request he didn't even need logins.

I searched the forum, I found 2 users and both gave up. So I decided to give it a go.

Thanks

Is this a free tv service? If not then I will close this thread.

Paid service with free channels. We could use a different MPD and Channel name. It's mostly Geolocked rather than paid.

All that was needed was this for headers, cookies, params:

payload["licenseRequest"] = base64.b64encode(challenge).decode('utf-8')

licence = requests.post(lic_url, json=payload, headers=headers)

I get a 403 forbidden even though I used a Canadian proxy (so I'm guessing the accessToken expired), but I don't get 400s or 415s, so the request is technically made the right way.

Yes, accessToken expired:

<attribute key="message:protection:notOnOrAfter">2024-02-18T13:52:03Z</attribute>

[shellcmd]

if you curl the license, still can get license response after long time.so token not expired, must something wrong with challenge. have no idea, maybe it is another site account relative to CDM, or need some signature.

Thanks to both of you. I was working on white_snake post right now.
Got a fresh CDM, fresh L3_correction files.

Edited my headers a bit to turn the "data" into "payload".
Added import base64 at the top of my headers file.

payload["licenseRequest"] = base64.b64encode(challenge).decode('utf-8')
                                                 ^^^^^^^^^

Thanks I reinstalled everything fresh now.

Tried to go deeper but couldn't figure it out. Only data I was able to pull is always the default_KID="4a1d29bff238b6cdbbe25ae423381113" that is in the MPD.

Looks like a double encryption MPD or something I'm not sure.

Here is the working key, still can't figure out how he pulled the second part.

Have you tried running the pywidevine script? What error do you get?

[white_snake]

Update: I'm suspecting they might be using TLS fingerprinting, so I tried curl_cffi, but I'm still getting 403s impersonating chrome120. So, as shellcmd said, there must be something else wrong.

Any news on how to get keys from Helix ?
