    Abstract: Rekeying in a storage system, including: receiving a request to rekey a first storage location of a storage system, wherein the first storage location is associated with a first cryptographic key; acknowledging completion of the request to rekey the first storage location without re-encrypting data stored at the first storage location of the storage system; and mapping a second cryptographic key identified by the request to rekey to the first storage location of the storage system.
