Adding a Digital Signature to a PDF: A Step-by-Step Guide
Introduction
In today’s digital age, digital signatures have become an essential tool for businesses and individuals to authenticate documents. A digital signature is a unique electronic signature that verifies the authenticity of a document, ensuring that it has not been tampered with or altered during transmission. In this article, we will guide you through the process of adding a digital signature to a PDF.
What is a Digital Signature?
A digital signature is a unique electronic signature that is created using a digital certificate, which is a public key infrastructure (PKI) certificate that is issued by a trusted certificate authority (CA). The digital signature is created by encrypting the document’s content using a private key and then decrypting it using the public key. The encrypted content is then verified by the recipient’s digital certificate, which ensures that the signature is genuine.
