# Digital Signatures

This tab contains the options related to exporting to a digitally signed PDF.

Selle käsu kasutamiseks...

Choose File - Export As - Export as PDF - Digital Signatures tab.

Digital signatures are used to ensure that the PDF was really created by the original author (i.e. you), and that the document has not been modified since it was signed.

The signed PDF export uses the keys and X.509 certificates already stored in your default key store location or on a smartcard.

The key store to be used can be selected under LibreOfficeDev - Preferences Tools - Options - LibreOfficeDev - Security - Certificate Path.

When using a smartcard, it must already be configured for use by your key store. This is usually done during installation of the smartcard software.

## Sertifikaat

### Sertifikaat PDF-dokumentide digiallkirjastamiseks

Allows you to select a certificate to be used for signing this PDF export.

### Vali

Avab dialoogi Sertifikaadi valimine.

All certificates found in your selected key store are displayed. If the key store is protected by a password, you are prompted for it. When using a smartcard that is protected by a PIN, you are also prompted for that.

Select the certificate to use for digitally signing the exported PDF by clicking on the corresponding line, then click OK.

All other fields on the Digital Signatures tab will be accessible only after a certificate has been selected.

### Sertifikaadi parool

Sisesta parool, mis kaitseb valitud sertifikaadiga seotud privaatvõtit. Tavaliselt on selleks võtmehoidla parool.

If the key store password has already been entered in the Select Certificate dialog, the key store may already be unlocked and not require the password again. But to be on the safe side, enter it nevertheless.

When using a smartcard, enter the PIN here. Some smartcard software will prompt you for the PIN again before signing. This is cumbersome, but that's how smartcards work.

### Asukoht, kontaktandmed, põhjus

Neile kolmele väljale võib soovi korral sisestada lisateavet PDF-ile rakendatava digiallkirja kohta (kus, kes ja miks allkirja andis). See teave salvestatakse vastavatele PDF-i väljadele ning on kättesaadav kõigile, kes loodavat PDF-faili vaatavad.

## Time Stamp Authority

During the PDF signing process, the TSA will be used to obtain a digitally signed timestamp that is then embedded in the signature. This (RFC 3161) timestamp will allow anyone viewing the PDF to verify when the document was signed.

If no TSA URL is selected (the default), the signature will not be timestamped, but will use the current time from your local computer.
