atharh commented on issue #4826: Invalid '*' corrupting connection password
URL: https://github.com/apache/incubator-superset/issues/4826#issuecomment-383455977
 
 
   This was a bug in sqlalchemy-utils: https://github.com/kvesteri/sqlalchemy-utils/issues/212
   
   The database password is encrypted with a broken padding scheme which strips `*` characters. See [here](https://github.com/apache/incubator-superset/blob/370d8a2bbe9c57a869bd4fc9726402fddb3cdb54/superset/models/core.py#L561).
   
   The fix is to upgrade sqlalchemy-utils and [use  PKCS5 padding with `EncryptedType`](http://sqlalchemy-utils.readthedocs.io/en/latest/data_types.html#module-sqlalchemy_utils.types.encrypted.encrypted_type).
