Open office document l.jpg

Before you enable the digital signatures feature in OpenOffice.org, you must obtain a digital certificate.

A digital certificate is a password-protected file that includes a variety of information, including the name and email address of the certificate owner, encryption key, issuing authority, and expiration period.

After obtaining a digital certificate you will have to install it on your machine.

Edit -> Preferences -> Advance -> View Certificates

-> Import.

To sign an OpenOffice.org document using the created certificate, choose :

File -> Digital Signatures

Press the Add button, select your certificate, and press OK to close the dialogs and sign the document.

You should see a tiny Seal icon in the Status bar, which indicates that the document has now been digitally signed. Other users can view the certificate by double-clicking on the Seal icon and pressing the View Certificate button.

The Seal icon indicates that the document has not been altered in any way. Modifying a signed document on your machine automatically removes the digital signature, and you must sign the document again once you're done editing it.

Using the digital signature feature, you can sign not only OpenOffice.org documents, but also OOoBasic macros. This allows the end users to verify the authenticity of a macro before executing it. There are two ways to sign a macro. You can either choose Tools -> Macro -> Digital Signature, or choose File -> Digital Signatures
