Define Digital Signature.
Answer
A Digital Signature is an advanced cryptographic mechanism verifying the absolute authenticity and absolute integrity of a digital document.
A Digital Signature is a highly advanced, mathematically unforgeable cryptographic stamp physically appended to a digital document or message. It strictly utilizes asymmetric public-key cryptography to absolutely guarantee non-repudiation (the sender cannot mathematically deny sending it) and data integrity (proving the file was not violently altered during network transit).
