Fully qualified class name: org.signserver.module.odfsigner.ODFSigner.
ODF Signer, which stands for Open Document Format Signer is a plug-in to SignServer that applies server side signature to documents in ODF format. It has been tested with OpenOffice.org 3.1.
ODF Signer supports only "invisible" signatures, that is unlike PDF signer there's no pictorial representation of the digital signature. When you open signed document in LibreOffice you can verify signature using toolbars, or the notifier in status bar (red mark), which notifies user that the document is digitally signed.
Other than standard worker properties, ODF Signer does not have any other custom ODF signer specific properties.
