Digital signatures use cryptographic techniques to provide a unique signature that is tied to the signer's identity, making it legally binding in many jurisdictions, including the United States. This method enhances the security of documents and simplifies the signing process, allowing for faster transactions and reduced reliance on paper-based methods.
