* A set of keys where a `UserKey` is protected by an encrypted public/private key-pair.
|
|
* The `UserKey` is used to encrypt/decrypt data, while the public/private key-pair is
|
|
* used to rotate the `UserKey`.
|
|
*
|
|
* The `PrivateKey` is protected by an `ExternalKey`, such as a `DeviceKey`, or `PrfKey`,
|
|
* and the `PublicKey` is protected by the `UserKey`. This setup allows:
|
|
*
|
|
* - Access to `UserKey` by knowing the `ExternalKey`
|
|
* - Rotation to a `NewUserKey` by knowing the current `UserKey`,
|
|
* without needing access to the `ExternalKey`
