7 years ago I've updated my code and verified that your generate key functions returns the same as my key (minus the dict for chat). Somehow the data still isn't decrypting...
class AESCipher(object):
def __init__(self, magic, access_key, password):
self.bs = 32
self.key = hashlib.md5(bytearray(access_key, "utf8") + magic).digest() + \
hashlib.md5(magic + bytearray(password, "utf8")).digest()
def encrypt(self, raw):
raw = self._pad(raw)
iv = Random.new().read(AES.block_size)
cipher = AES.new(self.key, AES.MODE_ECB, iv)
return base64.b64encode(iv + cipher.encrypt(raw))
def decrypt(self, enc):
enc = base64.b64decode(enc)
iv = enc[:AES.block_size]
cipher = AES.new(self.key, AES.MODE_ECB, iv)
return self._unpad(cipher.decrypt(enc[AES.block_size:])).decode('utf-8')
def _pad(self, s):
return s + (self.bs - len(s) % self.bs) * chr(self.bs - len(s) % self.bs)
@staticmethod
def _unpad(s):
return s[:-ord(s[len(s) - 1:])]

Awesome work Robert but I'm running Home Assistant(.io) which runs on Python, so I would like to port it.
Based on https://github.com/robertklep/nefit-easy-client/blob/master/lib/encryption.js#L11-L12
Would you be able to provide me with an example of the input and output of the function so I can verify that my code is working since I'm getting an empty string back. Random values should suffice.
function generateKey(magicKey, id_key_uuid, privatePassword)
