I keep my secret key inside a CFS encrypted file system.  If I am not
logged on, it is not available to anyone; if I am logged on it is still
only available to my login.  And if someone stole the machine they would
have two levels of encryption to break (CFS and the secret key pass

(Please, everyone, let me know if I am deluding myself!)

cfs is a Debian package.
