How to Add a Signature Field to a File in Acrobat

Adobe Acrobat has two types of signatures available for documents. They are a certifying signature and an approval signature. A certifying signature verifies the content of the document, while an approval signature works just like a handwritten signature on contracts and other legal documents. The difference between a handwritten signature and a digital signature is that a digital signature is extremely difficult to forge. It encrypts the information in the signature which is unique to the signer and contains an encrypted key. Adding a signature field to a file in Acrobat can help reduce paper usage and provide added security.
