Before you sign a document, you need to draw a signature field where the signature is placed, get a digital ID, and create the signature.

Digital ID is the identity of a person/organization, which contains your name, Email address, a serial number, an expiration date, and the name of the company. A digital ID contains two keys, one is a public key (certificate) that is used to encrypt or lock data, and the other is a private key that is used to decrypt or unlock data that is encrypted.

Quick PDF Sign enables you to create your self-signed signatures (ink signatures) and add the signature to the page directly. You don’t need to create different signatures for different roles.
