See also "Enable right-to-left languages" on page 55 Customizing signature properties using seed values Seed values offer additional control to document authors by letting them specify which choices a user can make when signing a document. By applying seed values to signature fields in unsigned PDFs, authors can customize options, automate tasks, and specify signature requirements for items such as certificates and timestamp servers. For more information on this topic, go to Acrobat Developer Center and search for the Acrobat 8.0 Security User Guide. Add a timestamp to signatures You can include the date and time you signed the document as part of your signature. Like signatures, timestamps are easier to verify when they're associated with a timestamp authority's trusted certificate. Including a timestamp helps to prove that the document wasn't changed after you signed it and reduces the chances of an invalid signature. You can obtain a timestamp from a third-party timestamp authority or from the certificate authority that issued your digital ID.
