Thanks 2nHxWW6GkN1l916N3ayz8HQoi for the reply
Just tested key posted by you and it's working

for my own learning purpose, May I know what I was doing wrong there?

You did some changes in that decrypt function or used different script?

[2nHxWW6GkN1l916N3ayz8HQoi]

I didn't bother with any existing scripts. I just read their js code and took what I needed directly from the page source. I won't bother going into detail since one of the site's devs is lurking around and making changes everytime a solution is found lmao. That's why you see so many scripts that don't work anymore. I think it's silly to even try to play this game.

Yes, Every time dev come up with something new, so all previous working scripts gets broken.
Do you mind if I PM you related to a python code?

I was trying to get key from this demo page : https://www.futurly.com/s/preview/courses/blender-architecture#6337f80fe4b05a534f0e3d5a

They have made changes in the decrypt function again

Now it's

if (i.decryptdata) 
{                       
var f = new Uint8Array(t.data)
           , g = f.subarray(16, 32)
           , v = f.subarray(48, 64);
             f = a(o(g), h(window.apkId.substring(16, 48)), {
             mode: u,
             padding: c
}),

I was referring this post by aadrl and this script by NBA456017

I have Made some changes in NBA's script as per the post of aadrl, but wrong key is getting generated

Here is changes i have made in Script posted by NBA

def _decrypt_key(data):
    tmp1 = data[16:32]
    tmp2 = data[48:64]
    apk_Id = apkId[:16] + apkId[48:]
    dec1 = AES.new(bytes.fromhex(apk_Id), AES.MODE_ECB)
    tmp3 = dec1.decrypt(tmp1)
    dec2 = AES.new(tmp3, AES.MODE_ECB)
    return dec2.decrypt(tmp2)

If someone could help me to understand what i am doing wrong, would be great.

In this specific example it was:

apk_Id = apkId[16:48]

not:

apk_Id = apkId[:16] + apkId[48:]

Every time you reload the page make sure you check again apkId and the aes function for changes.

Issue resolved now

For a particular site, the substring values (e.g. f = a(o(g), h(window.apkId.substring(16, 48)) are changing every time page is refreshed no matter how quickly I do it. Is it supposed happen like this?

Until a few days ago, I was able to decrypt the video using the script, but now its not possible. I will provide the apkId and the m3u8 link, can someone check from their end and let me know if its getting decrypted?

Isn't this one outdated?

I had the script posted in the current thread working until recently before I believe the site devs set the period for substring value changes to very low (may be every second or so). Th same script works on the other sites that were posted here before (e.g. futurly.com) as those dont change the substring values nearly as often (maybe once a day or so).

So for example, if its using 0:32 this moment, on next page refresh (even if done within 2-3 seconds) it might use :9+41: and so on.

How do I tackle this issue? (Someone I know has a workaround, but is asking money for giving out the solution. So I didnt bother asking him again :P)

I am not sure if I am clearly passing on the message here, its quite hard on explain in plain text :/
