Abstract
A method of efficient rekey in a transparent decrypting storage array includes receiving an instruction to rekey data on a storage array, wherein the instruction identifies first encryption information and second encryption information. The method further includes decrypting, by a processing device of a storage array controller, the data using the first encryption information to generate decrypted data. The method further includes encrypting the decrypted data using the second encryption information to generate encrypted data.
