Answer 1

 def decrypted(self) -> str:
    _pwd = base64.b64decode(self._key)
    _salt = base64.b64decode(self._salt)
    _aes = Crypto.Cipher.AES.new(_pwd, Crypto.Cipher.AES.MODE_CBC, _salt)
    _text = base64.b64decode(self._encrypted_str)
    _decode = _aes.decrypt(_text).decode('utf-16')
    _regex = '[a-zA-Z0-9 +-,\/ ]+'
    return re.findall(_regex, _decode)
