Adding digital signature to PDF involves incorporating electronic signatures into PDF documents. Digital signatures function as a form of identity verification, similar to handwritten signatures, ensuring the authenticity and integrity of documents in a digital environment.
Digital signatures have significant practical applications in various industries. They enhance the security of financial transactions, legal contracts, and other sensitive documents. Historically, the advent of asymmetric cryptography was a key development, enabling the creation of unique digital signatures that are both verifiable and tamper-proof.
