Cryptoperiod recommendations
Web• A cryptoperiod is the time span during which a particular cryptographic key can be used for its defined purpose. Considerations for defining the cryptoperiod include, but are not limited to, the strength of the underlying algorithm, size or length of the key, risk of key compromise, and the sensitivity of the data being encrypted. WebFeb 24, 2024 · Based on the above criteria, NIST recommends that the maximum cryptoperiod of private keys associated to certificates should be between one and three years and should be shorter than the cryptoperiod of the corresponding public key.
