A paragraph signature includes meta-data for the user who created the signature and the date the signature was created. Either Valid or Invalid is displayed as text at the end of a paragraph signature. By default, it displays Valid. If the paragraph is modified in any way after the paragraph signature is added, the signature changes to Invalid.
Upon saving a document, any Invalid paragraph signatures are automatically deleted.
A paragraph signature will indicate whether or not a particular paragraph has been modified at any time after the signature was inserted. Multiple paragraph signatures can be added, and each signature is independent from each other.
After navigating to Paragraph Signature in the More Fields dialog, click Insert to open the Select Certificate dialog.
A paragraph signature will always be inserted at the end of the currently selected paragraph. If the text cursor is not currently located within a paragraph of text, the Select Certificate dialog will not open.
The Select Certificate dialog lists any of your digital certificates that are available for use. Choose the desired certificate and select Sign to insert a paragraph signature using the chosen digital certificate.
You must have a digital certificate in order to begin Applying Digital Signatures.
