- `context_values`: are values like the bucket and object name and other information which should be cryptographically bound to the KEK.

To summarize for any encrypted object there exists (at least) three different keys:

- [OEK](#oek): A secret and unique key used to encrypted the object, stored in an encrypted form as part of the object metadata and only loaded to RAM in plaintext during en/decrypting the object.

To perform bi-directional replication, repeat the above process on the target site - this time setting the source bucket as the replication target. It is recommended that replication be run in a system with at least two CPU's available to the process, so that replication can run in its own thread.
