Remove the first and last character from the above apkId to get the actual apkId (Source : https://forum.videohelp.com/threads/408196-howto-deal-with-HLS-128-bit-aes-encrypted-t...-version/page2)

Python Script Decrypt (Change apkId and download timestamp file in script folder) :

import binascii
from Crypto.Cipher import AES

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

apkid = '63663737616335663033343635376566'

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())

Your key is wrong,the correct key is :

how did you get this key? while running provided script by sidman I also get the key which sidman got i.e. 59ace6010edd4ee2e5bf169e5f661863

Can N_m3u8DL-RE automate this entire process. If not, can you provide some general steps to automate the process ?

[swappyison]

why do i get this error,
ValueError: Incorrect AES key length (17 bytes)

i have tried the same script as this, import binascii
from Crypto.Cipher import AES

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

apkid = '63663737616335663033343635376566'

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())

Finding error can anyone help

[para8ox]

Earlier I used to download videos hosted on graphy but now I'm getting this error "ERROR: Padding is invalid and cannot be removed."
How to get rid of this so that we can download videos from it.

[para8ox]

Can anyone help me with the error, padding is invalid and cannot be removed, I tried 2-3 scripts and the key I got is different and I tried them all but everytime same error occurs.


Earlier they used to work, but now I'm getting this error, kindly help me please.

[LittleSoldier]

If you need some help from here to solve your problem then please provide some necessary information

1. ApkId
2. m3u8 URL

[para8ox]

Thanks a lot for your reply, but I was searching for it from last half an hour and just now it worked for me. Still thanks bro

[LittleSoldier]

@para8ox

I am happy to hear that you got a solution on your own
If you feel comfortable you can share here what you've figured out for future reference to everyone

[para8ox]

Sure, I searched on the forum and found that the solution is already provided here, just we need to understand it.

https://forum.videohelp.com/threads/408196-howto-deal-with-HLS-128-bit-aes-encrypted-t...e3#post2716234

This is the link from where I got the solution,

• In our script we simply have to change the range of apkID that needs to be processed to get the actual key.
• So steps are very simple, go to above link and there is one SS attached by aadrl, go to the source tab and then open that .min.js file and inside that you'll find apkId range.
• Put that range in the script and then run it. You'll surely get the working key.

@para8ox Great Catch...

Graphy often changes that range.

When we use the Script posted by @NBA456017 it generates a wrong key and fails to decrypt the file

I had also encountered the same problem in the past but I followed the same steps suggested by @aadrl and managed to get my videos
