This commit fixes a layout issue w.r.t. the KMS Quickstart guide. The problem seems to be caused by docs server not converting the markdown into html as expected. This commit fixes this by converting the ordered list into subsections.

# KMS Guide [](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 an unique object key which is protected by a master key
|
|
managed by the KMS.
|
|
|
|
## Quick Start
|
|
|
|
MinIO supports multiple KMS implementations via our [KES](https://github.com/minio/kes#kes) project. We run
|
|
a KES instance at `https://play.min.io:7373` for you to experiment and quickly get started. To run MinIO with
|
|
a KMS just fetch the root identity, set the following environment variables and then start your MinIO server.
|
|
If you havn't installed MinIO, yet, then follow the MinIO [install instructions](https://docs.min.io/docs/minio-quickstart-guide)
|
|
first.
|
|
|
|
#### 1. Fetch the root identity
|
|
As the initial step, fetch the private key and certificate of the root identity:
|
|
|
|
```sh
|
|
curl -sSL --tlsv1.2 \
|
|
-O 'https://raw.githubusercontent.com/minio/kes/master/root.key' \
|
|
-O 'https://raw.githubusercontent.com/minio/kes/master/root.cert'
|
|
```
|
|
|
|
#### 2. Set the MinIO-KES configuration
|
|
|
|
```sh
|
|
export MINIO_KMS_KES_ENDPOINT=https://play.min.io:7373
|
|
export MINIO_KMS_KES_KEY_FILE=root.key
|
|
export MINIO_KMS_KES_CERT_FILE=root.cert
|
|
export MINIO_KMS_KES_KEY_NAME=my-minio-key
|
|
```
|
|
|
|
#### 3. Start the MinIO Server
|
|
|
|
```sh
|
|
export MINIO_ACCESS_KEY=minio
|
|
export MINIO_SECRET_KEY=minio123
|
|
minio server ~/export
|
|
```
|
|
|
|
> The KES instance at `https://play.min.io:7373` is meant to experiment and provides a way to get started quickly.
|
|
> Note that anyone can access or delete master keys at `https://play.min.io:7373`. You should run your own KES
|
|
> instance in production.
|
|
|
|
## Configuration Guides
|
|
|
|
A typical MinIO deployment that uses a KMS for SSE-S3 looks like this:
|
|
```
|
|
┌────────────┐
|
|
│ ┌──────────┴─┬─────╮ ┌────────────┐
|
|
└─┤ ┌──────────┴─┬───┴──────────┤ ┌──────────┴─┬─────────────────╮
|
|
└─┤ ┌──────────┴─┬─────┬──────┴─┤ KES Server ├─────────────────┤
|
|
└─┤ MinIO ├─────╯ └────────────┘ ┌────┴────┐
|
|
└────────────┘ │ KMS │
|
|
└─────────┘
|
|
```
|
|
|
|
In a given setup, there are `n` MinIO instances talking to `m` KES servers but only `1` central KMS. The most simple
|
|
setup consists of `1` MinIO server or cluster talking to `1` KMS via `1` KES server.
|
|
|
|
The main difference between various MinIO-KMS deployments is the KMS implementation. The following table
|
|
helps you select the right option for your use case:
|
|
|
|
| KMS | Purpose |
|
|
|:---------------------------------------------------------------------------------|:------------------------------------------------------------------|
|
|
| [Hashicorp Vault](https://github.com/minio/kes/wiki/Hashicorp-Vault-Keystore) | Local KMS. MinIO and KMS on-prem (**Recommended**) |
|
|
| [AWS-KMS + SecretsManager](https://github.com/minio/kes/wiki/AWS-SecretsManager) | Cloud KMS. MinIO in combination with a managed KMS installation |
|
|
| [FS](https://github.com/minio/kes/wiki/Filesystem-Keystore) | Local testing or development (**Not recommended for production**) |
|
|
|
|
The MinIO-KES configuration is always the same - regardless of the underlying KMS implementation.
|
|

## Auto Encryption
|
|
|
|
Optionally, you can instruct the MinIO server to automatically encrypt all objects with keys from the KES
|
|
server - even if the client does not specify any encryption headers during the S3 PUT operation.
|
|
|
|
Auto-Encryption is especially useful when the MinIO operator wants to ensure that all data stored on MinIO
|
|
gets encrypted before it's written to the storage backend.
|
|
|
|
To enable auto-encryption set the environment variable to `on`:
|
|
```
|
|
export MINIO_KMS_AUTO_ENCRYPTION=on
|
|
```
|
|
|
|
> Note that auto-encryption only affects requests without S3 encryption headers. So, if a S3 client sends
|
|
> e.g. SSE-C headers, MinIO will encrypt the object with the key sent by the client and won't reach out to
|
|
> the KMS.
|
|
|
|
To verify auto-encryption, use the `mc` command:
|
|
|
|
```
|
|
mc cp test.file myminio/bucket/
|
|
test.file: 5 B / 5 B ▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓ 100.00% 337 B/s 0s
|
|
|
|
mc stat myminio/bucket/test.file
|
|
Name : test.file
|
|
...
|
|

|
|
X-Amz-Server-Side-Encryption: AES256
