👉 In cryptography, "meted" is a term used to describe a cryptographic key that is derived from a master secret or code book. It's often used in block cipher algorithms where it's used as a source of randomness for generating additional keys. This concept is important because it allows the algorithm to generate multiple keys without having to re-key any of them. The original master secret can be reused, which helps protect the integrity and security of the data being transmitted. In practice, meted keys are
