Key signature (cryptography)

In cryptography, a key signature refers to a cryptographic primitive that provides assurance of the authenticity and integrity of a message or data. It is generally associated with techniques used in public key cryptography, where a user can create a digital signature that can be verified by others using the sender's public key. ### Key Concepts: 1. **Digital Signature**: A digital signature is the cryptographic equivalent of a handwritten signature or a stamped seal but much more secure.
