Working with digital signatures (Windows)

 You can add a digital signature to a document in Acrobat to attest to something about the document in its current state. A digital signature, like any other signature, identifies a person or entity signing a document. In acrobat, a digital signature can appear on a page in many different forms – a handwritten name, a logo or graphic, or some text explaining the purpose of the signing. The particular appearance of the signature is determined by the signature handler, which is a plug –in that works with Acrobat.
