Digitally sign a document

How a PDF is digitally signed depends on how it was created. In most cases, a signature field will have already been added to the document in preparation for your signature. Such documents might also be certified. In some cases, however, you might need to add your own signature field before signing.  Fortunately, Revu makes it simple to do this.

If you don't yet have a Digital ID, you must first create one. See Managing Self-Signed Digital IDs.

Documents you've been given to sign might be certified. Some certified documents don't allow any changes to be made to them after certification.

If a digitally signed PDF is combined with another PDF, any signatures that were placed are automatically cleared and the resulting, combined document must be signed again. To avoid this situation, either combine PDFs before signing or use Sets to view separate, signed PDFs as a single collection. Another option that preserves the signature in this situation is to create a PDF package.

Documents that have been digitally signed are automatically locked for editing and their security status can't be changed unless the signatures are cleared. Operations that would change the document—adding or deleting pages, flattening markups, running OCR, or adding new form fields—aren't permitted or available for these documents.
