Obtain key from EXT-X-KEY local key instead of public URL

[lovedownload]

hi,

I am using streaming app instead of web browsers so can't use WidevineProxy to generate key. I tried and read a lots of thread but still cannot resolve my issue, here are details

1. URL

http://vod004-gb-hls1-prd-cf.cdn.skycdp.com/100e/skyplayer/VCD/VGC/bsky_sp_football/TITL0000000007962577/138beb30-233a-4b44-8f47-e068b8443ded-S/encrypted/30ba3f0f-8afa-4659-948b-523cf301ccf2/M3062118-720-3000/M3062118-720-3000_v.m3u8

2. Request and Response headers

I found the Key and IV but don't know how to decrypt to key:key

#EXTINF:10, no desc
M3062118-720-3000_v_0.ts

It led to error in N_m3u8DL-RE in the last step

Muxed Failed
An unrecoginzed encrypted detected
Invalid data found when processing input

Any help are appreciated.

As I described, I am using streaming app (Sky Go) and here what I got by using Proxyman

http://vod004-gb-hls1-prd-cf.cdn.skycdp.com/100e/skyplayer/VCD/VGC/bsky_sp_football/TITL0000000007962577/138beb30-233a-4b44-8f47-e068b8443ded-S/encrypted/30ba3f0f-8afa-4659-948b-523cf301ccf2/M3062118-720-3000/M3062118-720-3000_v.m3u8

Thank you bro, but I am a noob, can you please tell me how to do it? Via Proxyman?

Yes, you can also save the intercepted content as a HAR file and upload it here for easy viewing by others
