Cryptoperiod recommendations
WebAlgorithms For symmetric encryption AES with a key that's at least 128 bits (ideally 256 bits) and a secure mode should be used as the preferred algorithm. For asymmetric encryption, … 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.
