WKS-KEY does not get decryption key

[HORDTHIONZAC]

So, I'm testing WKS-KEY program to get decryption key for Bitmovin DRM demo. I have this key:

eb676abbcb345e96bbcf616630f1a3da:100b6c20940f779a4589152b57d2dacb

When trying to run program, it gives me an error:

ERROR:cdm.cdm:unable to parse license - check protobufs

I have extracted CDM from Android Studio, and edited l3.py and getPSSH.py files.

Any solutions?

Too much information. And what you have posted includes all the details needed for a CDN to ban your CDM. I would remove it and remove your link to files!

Secondly. You are using a modified l3.py with all sorts of crap in it. For proving your CDM working at bitmovin' just use a straight l3.py

pssh = input('\nPSSH: ')
lic_url = input('License URL: ')

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=headers.headers)
    license_b64 = b64encode(widevine_license.content)
    wvdecrypt.update_license(license_b64)
    Correct, keyswvdecrypt = wvdecrypt.start_process()
    if Correct:
        return Correct, keyswvdecrypt   
correct, keys = WV_Function(pssh, lic_url)

print()
for key in keys:
    print('--key ' + key)

Secondly the curl of your license is of a proxy not the license itself.
Thirdly, the good news is your CDM works.

Fourthly, bad news, you've posted your whole CDM for the World to download. I have just used it and now can everyone else.

wks-key link removed

The device can still be identified from your log file; best to remove that too.

Sorry, I have downloaded wks-keys from github. Where you got l3.py file?

I downloaded wks-key from github: https://github.com/larsk2/kks
There is so many useless information, that gives me an error.
Thank you for l3.py fixed program!
