Abstract
An online key stored by a remote service is generated or otherwise obtained, and a storage media (as it applies to the storage of data on a physical or virtual storage media) master key for encrypting and decrypting a physical or virtual storage media or encrypting and decrypting one or more storage media encryption keys that are used to encrypt a physical or virtual storage media is encrypted based at least in part on the online key. A key protector for the storage media is stored, the key protector including the encrypted master key. The key protector can be subsequently accessed, and the online key obtained from the remote service. The master key is decrypted based on the online key, allowing the one or more storage media encryption keys that are used to decrypt the storage media to be decrypted.
