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 34):
A non-transitory computer-readable storage medium comprising executable instructions that, if executed by one or more processors of a computer system, cause the computer system to at least:\n determine a durability duration based at least in part on parameters included in an obtained request for a first cryptographic key; encrypt the first cryptographic key such that the first cryptographic key is decryptable using a second cryptographic key, wherein the parameters of the request indicate that the second cryptographic key has a limited lifetime before being destroyed in accordance with a durability duration; and cause the first cryptographic key to be available for use for a period of time that ends after the limited lifetime for the second cryptographic key has passed.
