WebCryptoperiod - A cryptoperiod is a specific time span during which a cryptographic key setting remains in effect. A key uses an algorithm to create ciphertext from plaintext and, for the receiver of the encrypted text, to decipher it. Once the cryptoperiod ends, the key is no longer available for either encryption or decryption.4
