Per feedback received on other patch sets, an example key manager driver is required to support ephemeral storage encryption and Cinder volume encryption -- see * https://blueprints.launchpad.net/nova/+spec/encrypt-cinder-volumes * https://blueprints.launchpad.net/nova/+spec/encrypt-ephemeral-storage The ConfKeyManager class reads its key from the project's configuration file and provides this key for *all* requests. As such, this key manager is insecure but allows the aforementioned encryption features to be used without further integration effort. To clarify the above statements, the configuration-based key manager uses a single, fixed key. When used to encrypt data (e.g., by the Cinder volume encryption feature), the encryption provides limited protection for the confidentiality of data. For example, data cannot be read from a lost or stolen disk, and a volume's contents cannot be reconstructed if an attacker intercepts the iSCSI traffic between the compute and storage host. If the key is ever compromised, then any data encrypted with the key can be decrypted. This commit copies the ConfKeyManager class from Nova as well as synchronizing changes with the key manager interface in Nova.
