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 21):
A computer-implemented method, comprising:\n obtaining a request for a first cryptographic key; selecting, based at least in part on parameters of the request indicating a durability duration, a public cryptographic key from a plurality of public cryptographic keys, wherein each of the plurality of public cryptographic keys has a corresponding private cryptographic key in a set of private cryptographic keys; applying the selected public cryptographic key to generate an encrypted first cryptographic key, the encrypted first cryptographic key being decryptable using a corresponding private key from the set of private cryptographic keys, the private cryptographic key being scheduled to be destroyed at a time corresponding to the durability duration; storing the encrypted first cryptographic key; and making the first cryptographic key available for use for an amount of time corresponding to the durability duration.
