import base64
import json


def decode_base64(data):
missing_padding = 4 - len(data) % 4
if missing_padding:
data += '=' * missing_padding
return base64.urlsafe_b64decode(data)


licenseServerUri = input('base64: ')
licenseServer = decode_base64(licenseServerUri).decode('utf-8')
licenseServerdata = json.loads(licenseServer)

keys = ""
for key in licenseServerdata['keys']:
kid = key['kid']
k = key['k']
keys += f"--key {decode_base64(kid).hex()}:{decode_base64(k).hex() } "
print(keys)




Run in this form
thank you

seems it need argparse module. i never used this method, i think you can easily find argparse usage with google, not complex.

by the way, the script works for decode clear key, right?
