I hope you have a means of passing that key on to some other official in your company if something were to happen to you. You could be hit by a truck on the way to work, God forbid. I have the passwords only I know in a sealed envelope in the company safe deposit box, just in case.
Heh, yeah, you get it.
The password to the HIPAA key currently lives in a safety deposit box at a bank here in SF.
