The entire source code has now been modified. Don't suggest another thread because nothing else will work right now.

Now, how do I obtain the key to download videos from the above URL?

[lomero]

more we talk about this site (there are already several threads in this forum about this site) and the more the code changes ...

or you are developer of this site ?? ....

i think it's better not to talk about this site anymore. if you want his videos, BUY THEM !!

[helloImNoob]

good, that shit took long to change lol, but maybe someone will again post solution soon

[CrymanChen]

Why not use some downloaders to solve this problem quickly if you want this video?

no downloader working without key. now getting hex key or base64 string is very tough.

Will it work on aes 128 encrypeted .m3u8 file without base64 string or spka string value?

how to use it?

[lomero]

you know google ?

type tubedigger and search it instead of asking here < how to use it? >

and stop to ask the same question also to other thread ...

you can try it Trial mode has 50% size limitation for downloading and 4 MB for recording.

Hey any new way we can download the videos now?

[DrQaatil]

hello guys. spka no longer exists.

[Silv3r]

Hey any new way we can download the videos now?

try use https://chrome.google.com/webstore/detail/stream-recorder-download/iogidnfllpdhagebkblkgbfijkbkjdmm in RecMode

[Silv3r]

hello guys. so i have made some progress but a long way to go. we can connect on telegram @srivallli_bot
so i did a little digging to how this encryption has changed. spka no longer exists.
1. on going through the source i have stumbled on new logics of decryption but yet to decipher to make a python script. lets do this together. if i dont reply here you know where to find me!

try use https://chrome.google.com/webstore/detail/stream-recorder-download/iogidnfllpdhagebkblkgbfijkbkjdmm in RecMode

just checked TubeDigger in RecMode works fine

I've been looking into this as a JS dev and I've sucessfully figured out how to download videos from the Spayee platform - got it working in a custom python script.

First, find the Course ID, which is in this line of script on the page:

coursePlayer.init("6319d189e4b0ce4578316957", "Preview", "", true, false, "normal", "", 0);

Or, run this JS code and it should get you the course ID:

document.body.outerHTML.split(`coursePlayer.init("`)[1].split(`"`)[0]

Then, find the ID of the video itself - you can either inspect element the sidebar and find the selected content page, then look at it's data-id, or you can run this line of JS code below to get the selected video's ID, or look for a URL like this in the network tab

https://<whatever.com>/s/preview/courses/<course ID>/videos/6337f80fe4b05a534f0e3d5a/get

Where 6337f80fe4b05a534f0e3d5a is the video ID for this video

Or, run this JS Code on the page to get the current video's ID:

document.querySelector("div.courseSubItem.enabled-true.selected").getAttribute("data-id")

Also, from this course page you will need the apkId, which is like the new version of the spka value. You can find it by running "apkId" in the browser console, or by running this code. This value for apkId will change every time you switch login (this only matters for paid courses where you must be logged in, but this value is linked to the /t/ value below). apkId will look something like this:

62313734323630386634656538646135

This is actually hex encoded version of used to be spka value - you'll use this to decrypt the m3u8 key later:

Hex decoded: b1742608f4ee8da5

Now you can connect to this endpoint, which is an API that gives you the m3u8 URL (If it is a paid course, you will need to be send a request with your login cookie)

https://<whatever.com>/s/preview/courses/<course ID>/videos/<video ID>/get

The result will be something like this

{
    "_id": "6337f80fe4b05a534f0e3d5a",
    "spayee:resource": {
        "spayee:title": "01 Introduction",
        "spayee:courseAssetType": "video",
        "spayee:type": "upload",
        "spayee:underProcess": false,
        "spayee:completed": true,
        "spayee:status": "Completed",
        "spayee:previewUrl": "assets/videos/6197321b0cf23d7cc6e572e1/2022/10/01/6337f80fe4b05a534f0e3d5a/6337f80fe4b05a534f0e3d5a",
        "spayee:coverVersion": 3,
        "isCaption": false,
        "spayee:allowWatermark": true,
        "spayee:autoplay": true,
        "spayee:availability": "always",
        "spayee:context": "",
        "spayee:description": "",
        "spayee:isContextHtml": false,
        "spayee:isDescriptionHtml": false,
        "spayee:tags": [
            ""
        ],
        "spayee:totalTime": 13.14,
        "spayee:progress": 100,
        "spayee:streamUrl": "https://d2qny97nu4rj64.cloudfront.net/spees/w/o/6197321b0cf23d7cc6e572e1/v/6337f80fe4b05a534f0e3d5a/u/pu/t/87bb35a36b01e0943ef12fa4e6f5ef7c/p/assets/videos/6197321b0cf23d7cc6e572e1/2022/10/01/6337f80fe4b05a534f0e3d5a/index.m3u8"
    },
    "drmPlayerSupport": false,
    "response": true
}

You can find the (encrypted) m3u8 URL in the JSON path: "spayee:resource" > "spayee:streamUrl"

In this URL, the element after "/t" (87bb35a36b01e0943ef12fa4e6f5ef7c in this case) is the only bit that changes per video, and this is based on your session ID (this only really matters if you are trying to download a paid course, but it means that when you log in on one browser, the old /t/ value will be invalidated and a new one will be generated, along with the apkId - the apkId and the URL have to match - you can no longer use the old one as it will lead you to getting an incorrect /k/timestamp key for m3u8 decryption later on - you must make sure the cookie you send to this endpoint is of your latest login).

https://d2qny97nu4rj64.cloudfront.net/spees/w/o/6197321b0cf23d7cc6e572e1/v/6337f80fe4b05a534f0e3d5a/u/pu/t/87bb35a36b01e0943ef12fa4e6f5ef7c/p/assets/videos/6197321b0cf23d7cc6e572e1/2022/10/01/6337f80fe4b05a534f0e3d5a/index.m3u8

Anyway, if you curl/download and look at this m3u8, you will see the AES-128 encryption line, with a URI of "k/timestamp", so replacing index.m3u8 in the URL with "k/timestamp" will give you the decryption key endpoint. URL will look like this:

https://d2qny97nu4rj64.cloudfront.net/spees/w/o/6197321b0cf23d7cc6e572e1/v/6337f80fe4b05a534f0e3d5a/u/pu/t/87bb35a36b01e0943ef12fa4e6f5ef7c/p/assets/videos/6197321b0cf23d7cc6e572e1/2022/10/01/6337f80fe4b05a534f0e3d5a/k/timestamp

However, this key itself is also encrypted, using the apkId value. You can decrypt it with this python code, where data is the 48 bytes you get from "k/timestamp" endpoint, and apkid is apkid (like 62313734323630386634656538646135)

def _decrypt_key(data, apkid):
    tmp1 = data[0:16]
    tmp2 = data[32:48]
    dec1 = AES.new(bytes.fromhex(apkid),AES.MODE_ECB)
    tmp3 = dec1.decrypt(tmp1)
    dec2 = AES.new(tmp3,AES.MODE_ECB)
    return dec2.decrypt(tmp2)

This gives you the 16 byte key that's used to encrypt both the video (and audio if it's separate) m3u8 chunks. You can write these bytes to a .bin file or something similar, then replace the URI= in the m3u8 for video (and also audio if it's separate).

For my script, I downloaded the key file and then all the chunks (.ts), then replaced each chunk with the full disk path
example:

#EXT-X-KEY:METHOD=AES-128,URI="k/timestamp",IV=0x496daa1c6914000e408c65cead91fc29
becomes
#EXT-X-KEY:METHOD=AES-128,URI="C:\Users\f1shy\Desktop\dltesting\key.bin",IV=0x496daa1c6914000e408c65cead91fc29


hls_2M_003.ts
becomes
C:\Users\f1shy\Desktop\dltesting\video\hls_2M_003.ts

Then, I used ffmpeg to download the video, and it works great - I made my own small python script to do this, but you could also just incorporate all of this into a script, for something like youtube-dl or streamlink - I'm not going to do that. If anyone has any more questions about this, or how to download the live courses (I've got that working too - some of the sites add an extra layer of AES encryption on the /get endpoint), feel free to ask me.

[CrymanChen]

Wow, this is really great and huge work.

I have to say this is really splendid. Thank you @f1shy-dev

[lomero]

@f1shy-dev

wow, great detailed explanation. thanks for share that

Excellent work. Thanks for sharing.

    tmp3 = dec1.decrypt(tmp1)
    dec2 = AES.new(tmp3,AES.MODE_ECB)

I cant get the data from timestamp value, please help

[CrymanChen]

@swappyison Use this:

import binascii
from Crypto.Cipher import AES

with open("timestamp", "rb") as file: 
    data = file.read()

apkid = '62313734323630386634656538646135'

def _decrypt_key(data, apkid):
    tmp1 = data[0:16]
    tmp2 = data[32:48]
    dec1 = AES.new(bytes.fromhex(apkid),AES.MODE_ECB)
    tmp3 = dec1.decrypt(tmp1)
    dec2 = AES.new(tmp3,AES.MODE_ECB)
    return dec2.decrypt(tmp2)

result = _decrypt_key(data, apkid)
hex_result = binascii.hexlify(result)
print(hex_result.decode())

To make this script run, please download the key file timestamp in advance, then put timestamp and this script in the same folder.
Then run this script in the CMD window. In the screenshot below, I renamed it as "apkid.py", the result will be very clean, it's just the key to decrypt the video and the audio.


[Attachment 72888 - Click to enlarge]

Be aware that you can make this line

apkid = '62313734323630386634656538646135'

into this one

apkid = input('\napkid: ')

if you are trying to download other episodes.

Hi thank you so much I got the keys, however i ran into another problem, downloading from ./N_m3u8DL-RE gave me this error.
