- `X-Amz-Server-Side-Encryption-Customer-Key`: Base64 encoded new key.
- `X-Amz-Copy-Source-Server-Side-Encryption-Customer-Key`: Base64 encoded current key.

Such a special COPY request is also known as S3 SSE-C key rotation.

### Server-Side Encryption with a KMS

SSE-S3 allows an S3 client to en/decrypt an object at the MinIO server using a KMS. The MinIO
server only assumes that the KMS provides two services:

MinIO supports multiple long term users in addition to default user created during server startup. New users can be added after server starts up, and server can be configured to deny or allow access to buckets and resources to each of these users. This document explains how to add/remove users and modify their access rights.

## Get started

# How to monitor MinIO server with Grafana [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

[Grafana](https://grafana.com/) allows you to query, visualize, alert on and understand your metrics no matter where they are stored. Create, explore, and share dashboards with your team and foster a data driven culture.

## Prerequisites

COMMANDS:
  generate  generate a new batch job definition
  start     start a new batch job
  list, ls  list all current batch jobs
  status    summarize job events on MinIO server in real-time
  describe  describe job definition for a job
```

### Generate a job yaml
```
mc batch generate alias/ replicate
```

### Start the batch job (returns back the JID)
```

MinIO server allows to throttle incoming requests:

- limit the number of active requests allowed across the cluster
- limit the wait duration for each request in the queue

Certificates are no secrets and sent in plaintext as part of the TLS handshake.

A subroute on a client must match a subroute on the server. So routes cannot be used for dynamic routing, unlike HTTP.

Handlers should remain backwards compatible. If a breaking API change is required, a new handler ID should be created.

## Setup & Configuration

A **Manager** is used to manage all incoming and outgoing connections to a server.

On startup all remote servers must be specified.
