I am questioning the security of the password system on

I saved a spreadsheet with a simple password. I then looked at it

directory of
about 10 files. I was unable to see the individual files, but I am
concerned
how much I can rely on this security.
I the password actually an encryption key? If so what encryption
algorythym
is being used. If the password is just a password, then I assume
that a hex
viewer and a unzip utility could view the files.
I use an encrypted partition for all of my data files, but my
concern is when
I back up to cd/dvd/dvd-ram.
thoughts?
The summary information is not encrypted. The document content
however is encrypted.
Try this to show how good the encryption is:
* Work on a copy of the OpenDocument/OpenOffice file.
* Change the file extension to .zip
* unzip the file using you favourite compression utility
* take a look at the files there and see what you can read (or not).
