Abstract
A method of modifying encryption of a storage system includes: receiving an instruction to rekey data on a storage system, wherein the instruction identifies first encryption information and second encryption information; determining that the instruction is authorized; decrypting, by a processing device of a storage system controller, the data using a current key included in the first encryption information to generate decrypted data; and encrypting, by the processing device of the storage system controller, the decrypted data using the second encryption information to generate encrypted data.
