Abstract:
Cryptographic keys are durably stored for an amount of time. A cryptographic key is encrypted so as to be decryptable using another cryptographic key that has a limited lifetime. The other cryptographic key can be used to decrypt the encrypted cryptographic key to restore the cryptographic key during the lifetime of the other cryptographic key. After the lifetime of the other cryptographic key, if a copy of the cryptographic key is lost (e.g., inadvertently and unrecoverably deleted from memory), the cryptographic key becomes irrecoverable.

Claim (Index 28):
A system, comprising:\n memory storing instructions which, if executed by one or more processors of the system, cause the system to at least:\n obtain a request for a first cryptographic key, wherein the request includes parameters indicating a durability duration for the first cryptographic key; \n select, based at least in part on the parameters, a second cryptographic key from a set of cryptographic keys; \n use the selected second cryptographic key to encrypt the first cryptographic key such that:\n for a first amount of time corresponding to the durability duration, the first cryptographic key is recoverable from the encrypted first cryptographic key; \n after the first amount of time has passed, the first cryptographic key is irrecoverable from the encrypted first cryptographic key; and \n the second cryptographic key is scheduled to be destroyed corresponding to the durability duration; and \n \n provide the first cryptographic key to be available, in response to the request, for use for an amount of time corresponding to the durability duration.
