If I could make a quick feature request - to be able to copy a password to the clipboard (pref. plain X11) instead of outputing otherwise (I've had a quick look for a way to do this to no avail). Also a util to securely erase a file a password was output to would be complimentary.
This was an interesting article,

Myself I'm still trying to figure how I'm getting incidents of MITM style data injection over a SSL vpn to a https webpage! (I can't do any more to make the physical machine itself more secure either - so I am assuming this is not the problem, and I'm not running any dodgy software otherwise.)
