WebCryptoperiod – The cryptoperiod (or key lifetime) is the time span during which a specific cryptographic key is authorized for use. Dual control – No single person is permitted to access or use the materials. Encryption – Process of converting information into an unintelligible form except to holders of a specific cryptographic key. WebThe time from creation to expiration is called the “cryptoperiod” of the key. Although the key may be revoked before its expiration, the cryptoperiod is the longest that a key should remain valid. 1 NIST has issued FIPS 140 -3 and no longer accepts FIPS 140 2 modules for validation.
