What are signatures in cyber security?

Question

Could someone tell me what are signatures in cyber security?

Answer 1

A signature in cybersecurity is a mathematical technique through which it validates the authenticity of a message, text, document, or software. It’s a digital substitute of a physical stamp, signature, or seal which verifies that the message or document hasn’t altered during the transit. These signatures encrypt the document and allow only the receiver or sender to access the information.
