Расшифровка файла с помощью модуля Fernet в Python ⇐ Python

[Anonymous]

def decrypt(self): if not os.path.exists(self.filename): raise Exception('File does not exist!') # Read the salt and HMAC digest from the separate file with open(self.filename + '.salt', 'rb') as file: k_sz = Fernet.key_size salt = file.read(k_sz) hmac_digest = file.read(hashlib.sha256().digest_size) here in the decrypt function i am trying to get the salt and hmac value stored in the encrypted file. But receiving the error

File "C:\python programs\test2.py", line 61, in decrypt k_sz = Fernet.key_size ^^^^^^^^^^^^^^^ AttributeError: type object 'Fernet' has no attribute 'key_size' i have tried .KEY_SIZE and Fernet(key=None).key_size then it says key value as none not expected
