# 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://min.io/docs/minio/linux/index.html#quickstart-for-linux) 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_ROOT_USER=minio
|
|
export MINIO_ROOT_PASSWORD=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 |
|
|
| [Gemalto KeySecure /Thales CipherTrust](https://github.com/minio/kes/wiki/Gemalto-KeySecure) | Local KMS. MinIO and KMS On-Premises. |
|
|
| [Google Cloud Platform SecretManager](https://github.com/minio/kes/wiki/GCP-SecretManager) | 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. Checkout the MinIO-KES [configuration example](https://github.com/minio/kes/wiki/MinIO-Object-Storage).

## Auto Encryption
|
|
|
|
Auto-Encryption is useful when MinIO administrator wants to ensure that all data stored on MinIO is encrypted at rest.
|
|
|
|
### Using `mc encrypt` (recommended)
|
|
|
|
MinIO automatically encrypts all objects on buckets if KMS is successfully configured and bucket encryption configuration is enabled for each bucket as shown below:
|
|
|
|
```
|
|
mc encrypt set sse-s3 myminio/bucket/
|
|
```
|
|
|
|
Verify if MinIO has `sse-s3` enabled
|
|
|
|
```
|
|
mc encrypt info myminio/bucket/
|
|
Auto encryption 'sse-s3' is enabled
|
|
```
|
|
|
|
### Using environment (not-recommended)
|
|
|
|
MinIO automatically encrypts all objects on buckets if KMS is successfully configured and following ENV is enabled:
|
|
|
|
```
|
|
export MINIO_KMS_AUTO_ENCRYPTION=on
|
|
```
|
|
|
|
### Verify auto-encryption
|
|
|
|
> 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 configured KMS.
|
|
|
|
To verify auto-encryption, use the following `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
|
|
...
|
|
Encrypted :
|
|
X-Amz-Server-Side-Encryption: AES256
|
|
```
|
|
|
|
## Encrypted Private Key
|
|
|
|
MinIO supports encrypted KES client private keys. Therefore, you can use
|
|
an password-protected private keys for `MINIO_KMS_KES_KEY_FILE`.
|
|
|
|
When using password-protected private keys for accessing KES you need to
|
|
provide the password via:
|
|
|
|
```
|
|
export MINIO_KMS_KES_KEY_PASSWORD=<your-password>
|
|
```
|
|
|
|
Note that MinIO only supports encrypted private keys - not encrypted certificates.
|
|
Certificates are no secrets and sent in plaintext as part of the TLS handshake.
