Actually it is almost trivial to open an encrypted Word or Excel file if you
encrypt using the built-in MS system. There are plenty of programs which
will open these files. I once used one to open a file in the office where
someone had forgotten the password, but I forget which one I used.

Three letters: EFS. (Encrypted File System)

With Windows? How do you make sure you export all the key(s) and
other data used for the encryption so that they don't fall into the
wrong hands or get lost if your boot drive is ever corrupted? I'm a
bit paranoid about any sort of encryption that's Windows-based, about
how much the encryption is tied to a particular user account or some
other odd values uniquely chosen and hidden away in the registry or on
the boot drive. For instance, services like iTunes, the new Napster,
MovieLink, and CinemaNow do this for their media files.


How physically secure is EFS anyway?

"With AEFSDR (Advanced EFS Data Recovery), protected files can be
decrypted, even when the system is not bootable so you cannot log on,
or when some encryption keys (private or master) have been tampered
with."
