This method replaces traditional handwritten signatures, providing a secure and efficient way to sign documents. Digital signatures use cryptographic techniques to create a unique signature that is linked to the document, making it tamper-evident. This means that any changes made to the document after it has been signed will invalidate the signature, ensuring that the original content remains unchanged.
