Writer Guide

Whenever someone changes something in the document, this change
breaks the digital signature.
On Windows operating systems, the Windows features of validating a
signature are used. On Solaris and Linux systems, files that are
supplied by Thunderbird, Mozilla or Firefox are used. For a more
detailed description of how to get and manage a certificate, and
signature validation, see “Using Digital Signatures” in the OOo Help.
To sign a document:
1) Choose File > Digital Signatures.
2) If you have not saved the document since the last change, a
message box appears. Click Yes to save the file.
3) After saving, you see the Digital Signatures dialog box. Click Add
to add a public key to the document.
4) In the Select Certificate dialog box, select your certificate and
click OK.
5) You see again the Digital Signatures dialog box, where you can
add more certificates if you want. Click OK to add the public key
to the saved file.
A signed document shows an icon in the status bar. You can double-
click the icon to view the certificate.
