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.

Removing personal data

You may wish to ensure that personal data, versions, notes, hidden information, or

recorded changes are removed from files before you send them to other people or

create PDFs from them.

In Tools > Options > OpenOffice.org > Security > Options, you can set OOo to

remind (warn) you when files contain certain information and remove personal

information automatically on saving.

To remove personal and some other data from a file, go to File > Properties. On the

General tab, uncheck Apply user data and then click the Reset button. This

removes any names in the created and modified fields, deletes the modification and

printing dates, and resets the editing time to zero, the creation date to the current

date and time, and the version number to 1.

To remove version information, either go to File > Versions, select the versions from

the list and click Delete, or use Save As and save the file with a different name.
