A digital signature is a mathematical technique used to validate the authenticity and integrity of a digital document, message or software. It's the digital equivalent of a handwritten signature or stamped seal, but it offers far more inherent security. A digital signature is intended to solve th...
Theoretically, you could skip that hash function part and simply run the file and the private key through some "signing algorithm" and still produce a "digital signature". However, if the file is so large, this would take a great deal of time. Besides, the resulting "signature" would also...
