Cryptoperiod

WebQuestion: a) Cryptoperiods A cryptographic key is a value (essentially a random string of bits) that serves as input to an algorithm, which then transforms plain text into ciphertext (and vice versa for decryption). One of the important characteristics that determines key strength is its cryptoperiod [1]. Or the length of time for which the key is authorised for use. WebJul 28, 2024 · A cryptoperiod is not a period of time, like a month, week, or year. Rather, a cryptoperiod represents the number of transactions that a key is valid for.
