# KMS Guide [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

MinIO uses a key-management-system (KMS) to support SSE-S3. If a client requests SSE-S3, or auto-encryption is enabled, the MinIO server encrypts each object with a unique object key which is protected by a master key managed by the KMS.

## Quick Start

 *
 * <ol>
 *   <li>A pipeline starts at its leaf step (or steps), which is created from either a callable
 *       block or a {@link ListenableFuture}.
 *   <li>Each other step is derived from one or more input steps. At each step, zero or more objects
 *       can be captured for later closing.
 *   <li>There is one last step (the root of the tree), from which you can extract the final result

  enum ReleaseResourcesReason {
    OUTPUT_FUTURE_DONE,
    ALL_INPUT_FUTURES_PROCESSED,
  }

  /**
   * If {@code allMustSucceed} is true, called as each future completes; otherwise, if {@code
   * collectsValues} is true, called for each future when all futures complete.
   */
  abstract void collectOneValue(int index, @ParametricNullness InputT returnValue);

  abstract void handleAllCompleted();

In the HTTP protocol, you can communicate to each path using one (or more) of these "methods".

---

When building APIs, you normally use these specific HTTP methods to perform a specific action.

Normally you use:

* `POST`: to create data.
* `GET`: to read data.
* `PUT`: to update data.
* `DELETE`: to delete data.

So, in OpenAPI, each of the HTTP methods is called an "operation".

## Metadata for tags { #metadata-for-tags }

You can also add additional metadata for the different tags used to group your path operations with the parameter `openapi_tags`.

It takes a list containing one dictionary for each tag.

Each dictionary can contain:

* `name` (**required**): a `str` with the same tag name you use in the `tags` parameter in your *path operations* and `APIRouter`s.

access modes, and other special-purpose flags....

   * @param newN the expected number of entries once duplicates are removed
   * @param duplicates a map of canonical {@link Entry} objects for each duplicate key. This map
   *     will be updated by the method, setting each value to false as soon as the {@link Entry} has
   *     been included in the new entry array.
   * @return an array of {@code newN} entries where no key appears more than once.
