Interoperability Production Credentials Password storage

Credentials for a Productions are stored as plain text in ^Ens.SecondaryData.Password and exposed as plain text via SQL table Ens_Config.Credentials which is not ideal as only admins should know the credentials.

I can create my own adapter etc... to store and use encrypted passwords but does anyone know if there is a standard way to do this in a Production?

Alternatively, am I missing how to secure this so the production can run and someone can monitor and operate a production without access to the SQL table or global?
