Notes Internet Password Field

I was done in by the Lotus Notes Internet Password hash in R5 today (yeah its ancient).
I changed my domain password and used some words wrapped in parentheses like the following (my Blue shoe). Normally this would be a decent password. But at our company passwords are synched from Active Directory to the Lotus Notes Internet password field. In that field in Notes anything inside parenthesis is presumed to be encrypted already. So anyone in the company looking in the right place could see my password in plain text!
