## Interface KeyProvider

- All Known Implementing Classes:
    JKSKeyProvider

      public interface KeyProvider

  Customizable key retrieval mechanism. Implementations should expect that retrieved keys will be cached. Further, each key will be requested non-concurrently (that is, no stampeding herds for the same key), although unique keys may be requested concurrently (unless you mark `getSecretKey` synchronized). Implementations must provide a constructor that accepts `TransparentDataEncryptionOptions` as the sole parameter.
