Help downloading an AES-128 encrypted video

[VinzOP]

Hi guys

I've recently payed for an HLS video, and I need to download it.
I've tried several codes using ffmpeg and N_m3u8DL-RE, but I figured that the problem is that the video is AES-128 encrypted, and I can't really find a master.m3u8 using dev tools.

What I have found are the next URLs:
1080.m3u8

https://hls2.videos.sproutvideo.com/c9a8ce796e95905e51bfb56668dec3de/c5336e6679d7b2316c858bd7089c6e55/video/1080.m3u8?Policy=eyJTdGF0ZW1lbnQiOlt7IlJlc291cmNlIjoiaHR0cHM6Ly9obHMyLnZpZGVvcy5zcHJvdXR2aWRlby5jb20vYzlhOGNlNzk2ZTk1OTA1ZTUxYmZiNTY2NjhkZWMzZGUvYzUzMzZlNjY3OWQ3YjIzMTZjODU4YmQ3MDg5YzZlNTUvKi5tM3U4P3Nlc3Npb25JRD0yZmU4YjQwYy1iY2ZjLTQ4NTAtYTQ0ZS0wNjI2NGE4YmEzMWEiLCJDb25kaXRpb24iOnsiRGF0ZUxlc3NUaGFuIjp7IkFXUzpFcG9jaFRpbWUiOjE3MTg4NzY5Nzh9fX1dfQ__&Signature=kV05VwnVSzxRkDVsKZ4c3bCe2QpN1QF8WjzIYHgdkAQDnDgHX48R8E7L8Bti7JM-bbZi7e5KsyaUTqMSSG7VNrDxHdccvbbMLlPtLTVb6qNkLC8RS-TFsY1crK6WbLcVu4Xizoa-TK7tB42Z8lGZcRFdvM0P7JaGaHT42ImXR0~3xe5iy~cxVGkJZy9xxRNQIPOWBakKzpjz0VbGS3ZzgH6VbfqZwzKiB7eSGoQUV2kTXPE5TjsmvO0d0QCA5oU1BWCjlGxLB0pLsfXw0kRbMMdsPUmSkq8PlWu9CxmsCuJu-Kd6UDalNQXwtd7tEeKoOw6Wk6-4khWyOBriAHgdEA__&Key-Pair-Id=APKAIB5DGCGAQJ4GGIUQ&sessionID=2fe8b40c-bcfc-4850-a44e-06264a8ba31a

Read many threads about this kind of encryption, but I can't find the right way to get things done.
I'm using a mac running OS Sonoma by the way.

Deep thanks!

Hi guys

Read many threads about this kind of encryption, but I can't find the right way to get things done.

Edit - Oops! It looks like I mistakenly pasted the wrong key. Thanks to @shellcmd for bringing this to my attention.

P.S. @VinzOP If you are still not able to decrypt it please post the actual video URL

how to do this when we cant login the website(even dont know which the site it is) with firefox? i only have one idea is make a get request to the key link, and then encode the response to base64, convert to hex. but the value not same to yours, can you give some tips?

i got base64 and hex:

@shellcmd

My Bad.. I accidentally pasted the wrong conversion of base64 to hex by my oversight

I've used the same workaround in Firefox to get that key.

[shellcmd]

ok, thanks. now i know how to handle this in firefox.

[VinzOP]

Thanks for all the answers.

Read the thread posted by dronem, where he explains how to download AES-128 encrypted HLS with hlsdl (not available for mac).
As I'm still trying to figure out how to download this video, I will provide all the details I can.

This is the site from where I payed for the stream.
As it's a rental, to watch the stream I need to be logged in. If this would be as easy as it is in Vimeo for example... where I can be logged in and find the video's URL encrypted in HTLM code using dev tools, copy-pasting it to the browser and downloading it as easy as right clicking and saving.

When I get access to the full video, what I'm getting now in dev tools is the next:

- index.m3u8

What I tried to do with it was to apply the next code found in other thread, and see what happens:

N_m3u8DL-RE "index URL" --custom-hls-method AES_128 --custom-hls-key KEY -M format=mkv -mt --save-name "NAME"

Terminal gives me this:

In this case, I can select the 1080 stream in the Index, and it creates the "NAME" folder but it doesn't download any real content, and stays processing at 0% until I quit terminal. Well, I also notice that it finds video streams without audio, but lets pass that for now.

If I try to download a single segment, and I apply the same code than for the last two operations, it actually download a 5Mb chunk. But the content is 00m00s, so I don't really understand.

So, maybe I'm not using the right code, or the right tool to put all together as it should.
What is weird is that when I used both keys provided by LittleSoldier and shellcmd, the results were the same.
Related to that, and still don't really understand how to convert a the 1080.key file to hex the right way. When I open the file in text reader, I see:

"ΩŸ¶>uís%!cóT>1Öd"

so I used ChatGPT with the promt to convert it to hex, and after encoding with utf-8 it gave me the following

cea59fc2b63e75c3ades2121c3b3543e31c39664

Can that be right?

Hope this gives more context.

[shellcmd]

yes can't download first segment. I think there should be some authorization data in m3u8 link's headers. try to add them to command use -H "key: value", you can use this for many times. the key: value part maybe cookie, authorization, token, refere or user-agent

[VinzOP]

What I see in headers are:

As this is a video that activates in its full version only when I log in, I now understand that it changes some values in its URL each time, so I have to grab new m3u8 urls to try to download it...

Applied some -h to my commands but still unsuccessful.
