Getting keys from CTV.ca

[X-static]

Hi,

I'm trying to download this movie https://www.ctv.ca/movies/the-last-picture-show/the-last-picture-show

I'm using WKS-KEY from here.

mpd: https://capi.9c9media.com/destinations/ctvmovies_hub/platforms/desktop/bond/contents/1138138/contentpackages/2452587/manifest.mpd
PSSH: AAAAUnBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAADIIARIQJc68rp9Dcta/ijEnoBCT1BoJYmVsbG1lZGlhIhFmZi04OGEzZDUyOS03OTAxMQ==
License: https://license.9c9media.ca/widevine

I'm also using this header file:

import requests

headers = {
    'Accept': '*/*',
    'Accept-Language': 'en-US,en;q=0.9,pt-PT;q=0.8,pt;q=0.7',
    'Connection': 'keep-alive',

    'Referer': 'https://www.ctv.ca/',

    'sec-ch-ua': '"Chromium";v="102", " Not A;Brand";v="99"',
    'sec-ch-ua-mobile': '?0',
    'sec-ch-ua-platform': '"Windows"',
}

I'm always getting this error:

xxxxxx@ubuntu:~/WKS-KEYS$ python l3.py start

    raise ValueError("Ciphertext with incorrect length.")
ValueError: Ciphertext with incorrect length.

I believe is something wrong with the header or PSSH, but tried deleting some lines from the header and always the same result.

Also tried with this PSSH I got from the mp4 KID:

AAAAMnBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAABISECXOvK6fQ3LWv4oxJ6AQk9Q=

Again, same error.

Can someone help me understand what I'm doing wrong? Thank you.

Thank you for the keys.

I tried with license curl (bash) instead of manifest.mpd and got the same error.

I'm using a VPN, don't know if it may affect the result.

Probably I didn't made it clear in my previous post, but I did that. Same ciphertext error.

[k2000]

you used your own CDM keys in WKSKEYS because the provided CDM keys are revoked

[X-static]

I see. How can I get working CDM Keys? Can I get them easily from my android phone? Are there some available do download?

Sorry. Still trying figure stuff out.

[k2000]

you can use one of these scripts.
