Passwords &
Protection
To encrypt
the document with a password for opening it, choose the first check
box. The Advanced tab allows you to choose an Encryption
Type. The options listed are those available on your
particular computer. So, if you need to share the file, you
might want to consider leaving the option as Office 97/2000 Compatible.
There are
programs available that will crack the password for Office files in
case a password is forgotten or lost. However, I'm sure you
can see how these programs could be used to also crack passwords for
files for which users are not supposed to have access. If you
are concerned about this, you may want to change the encryption type
from Office 97/2000 Compatible to something else.
You can
also add a password that would be necessary to modify the file, or
choose the Read-only recommended check box. These two
features are different. Read-only recommended
makes a suggestion to the user who opens the file that no changes
should be made. However, they can still modify the file and
save it under a different name. Adding a password to modify
the file ensures that to make changes the user must know the
password.
Digital
signatures may or may not be legally binding in a court of law.
You should check with the appropriate jurisdiction to find out if
the signature can be legally binding. Essentially, in Office
XP, a certificate is used to produce a digital signature. The
certificate used to create this signature confirms that the macro or
document originated from the signer, and the signature confirms that
it has not been altered. When you set the macro security level, you
can run macros based on whether they are digitally signed by a
developer on your list of trusted sources. To add, remove, or
view the properties of a digital signature, choose the Digital
Signature button. The Digital Signature dialog box
is shown below.
The Protect
Document button protects the document for tracked changes,
comments and forms. You can add a password here as well:
