how to fix: for key in keys: TypeError: 'NoneType' object is not iterable

[googol]

i have the code:

def decrypt_keys():
wvdecrypt = WvDecrypt(pssh)
raw_challenge = wvdecrypt.get_challenge()
challenge_b64 = b64encode(raw_challenge).decode()
widevine_license = requests.post(
url=lic_url, data=raw_challenge, headers=headers, timeout=10)
license_b64 = b64encode(widevine_license.content)
wvdecrypt.update_license(license_b64)
keys = wvdecrypt.start_process()
if keys:
return keys
keys = decrypt_keys()
for key in keys:
print("\n[green]+ [INFO] KEY: --key [/green]" + key)


and the error when I get the keys is:

for key in keys:
TypeError: 'NoneType' object is not iterable

Can someone help me fix the above error? Thanks!

wvdecrypt returns a tuple containing an indicator of succes or otherwise and a list object containing keys.
You are saying your keys are equal to the tuple
Try this:

def WV_Function(pssh, lic_url, cert_b64=None):
    wvdecrypt = WvDecrypt(init_data_b64=pssh, cert_data_b64=cert_b64, device=deviceconfig.device_android_generic)                   
    widevine_license = requests.post(url=lic_url, data=wvdecrypt.get_challenge(), headers=None)
    license_b64 = b64encode(widevine_license.content)
    wvdecrypt.update_license(license_b64)
    Correct, keyswvdecrypt = wvdecrypt.start_process()
    # chain any multiple keys with --key at the start
    if Correct:
        mykeys = ''
        for key in keyswvdecrypt:
            mykeys += '--key' + key
    print(mykeys)
    return mykeys

thank you, I tried your instructions, it doesn't give me any error but I also don't get the keys

Then you have error elsewhere but not code errors as such. Probably something wrong with headers, pssh or the license. Who knows? It you check the value in 'Content' if it doesn't say 'Success' the cdm failed to do its job for some reason. Intercepting the command window in httptoolkit may give you more help. Or try sprinkling print(variable-name) statements throughout your code to make sure you've got what you're expecting at various stages.

My code listed headers as none - you may need headers to your site so add this example header file

headers = {
    'Accept': '*/*',
    'Accept-Language': 'en-GB,en;q=0.7',
    'Connection': 'keep-alive',
}

and change headers=None in my original code to header=headers.

But you may need to edit my minimal headers to whatever your curl of the license gives.

Thank you! i tried again with wks-keys also failed to get the keys, which before wks-keys and that re-mod worked fine. i tried to get keys by getwvkeys got 4 keys but those keys are not viewable either. maybe that site has fixed the error already. (I don't speak English so I have to use google translate, hope you understand.)

- There is one more problem I hope you can help me with:

I got a link but it contains tokens and only lasts a few hours like this:

https://abc.xyz/MzIxNzg5MzR8azFzcG9ydDFmcGxfNzIwcC5zdHJc2MTc3MDIx/manifest.mpd

Does anyone know how the php code automatically gets the link like this:

http://mysite.xyz/manifest.mpd

Thanks!

That doesn't make much sense as you originally said you could not see any keys

i tried to get keys by getwvkeys got 4 keys but those keys are not viewable either.

GetVWKeys returned keys but you cannot see them?? How do you know keys were returned

maybe that site has fixed the error already. (I don't speak English so I have to use google translate, hope you understand.)

??? not very well.

Here is the bare minimum change to your original code

def decrypt_keys():
wvdecrypt = WvDecrypt(pssh)
raw_challenge = wvdecrypt.get_challenge()
challenge_b64 = b64encode(raw_challenge).decode()
widevine_license = requests.post(
url=lic_url, data=raw_challenge, headers=headers, timeout=10)
license_b64 = b64encode(widevine_license.content)
wvdecrypt.update_license(license_b64)
correct , keys = wvdecrypt.start_process()
if correct:
    return keys


keys = decrypt_keys()
for key in keys:

thanks bro, I will try it
