- [KEK](#kek): A secret and unique key used to en/decrypt the OEK and never stored anywhere. It is(re-)generated whenever en/decrypting an object using an external secret key and public parameters.
- [EK](#ek): An external secret key - either the SSE-C client-provided key or a secret key generated by the KMS.

#### Content Encryption

   * Tests equality of {@link Hashing#goodFastHash} instances. This test must be separate from
   * {@link #testSeededHashFunctionEquals} because the parameter to {@code goodFastHash} is a size,
   * not a seed, and because that size is rounded up. Thus, {@code goodFastHash} instances with
   * different parameters can be equal. That fact is a problem for {@code
   * testSeededHashFunctionEquals}.
