Abstract
One example method includes receiving clear text data at a storage system, generating, at the storage system, a clear text data encryption key, requesting a key management system to encrypt the clear text data encryption key with a master key to create an encrypted data encryption key, and the requesting is performed by the storage system, receiving, at the storage system, the encrypted data encryption key from the key management system, encrypting, at the storage system, the clear text data with the clear text data encryption key to create encrypted data, and storing, together, the encrypted data and the encrypted data encryption key.
