1 (D)

Synonym for "cryptoperiod". Deprecated Definition: IDOCs SHOULD NOT use this term with definition 1 because a key's cryptoperiod may be only a part of the key's lifetime. A key could be generated at some time prior to when its cryptoperiod begins and might not be destroyed (i.e., zeroized) until some time after its cryptoperiod ends.
