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 37):
The non-transitory computer-readable storage medium of  claim 34 , wherein the executable instructions, further cause the computer system to at least:\n obtain an application programming interface request to extend the durability duration; select, based at least in part on the request, a second public cryptographic key from the plurality of public cryptographic keys; use the second cryptographic key to generate an encrypted second key; store the encrypted second cryptographic key; and update a database to indicate a new durability duration.
