Abstract
A method of decommissioning a key in a decryption storage system includes scanning a storage system to identify metadata associated with a current key to be decommissioned. The method further includes encrypting, with the current key, data corresponding to the metadata to generate encrypted data. The method further includes decrypting the encrypted data with a target key to generate decrypted data. The method further includes modifying, by a processing device, the metadata to identify the target key to generate modified metadata. The method further includes storing the decrypted data and the modified metadata to the storage system.
