# /sys/rotate/config

The `/sys/rotate` endpoint is used to configure automatic key rotation.

### Configure automatic key rotation

This endpoint configures the automatic rotation of the backend encryption key. By default, the key is rotated after just under 4 billion encryptions, to satisfy the recommendation of [NIST SP 800-38D](https://csrc.nist.gov/publications/detail/sp/800-38d/final). One can configure rotations after fewer encryptions or on a time based schedule.

### Create or update the auto rotation configuration

| Method | Path                 |
| ------ | -------------------- |
| `POST` | `/sys/rotate/config` |

#### Parameters

* `max_operations` `(int: 3865470566)` - Specify the limit of encryptions after which the key will be automatically rotated. The number must be between 1,000,000 and the default.
* `interval` \`(string: "") - If set, the age of the active key at which an automatic rotation is triggered. Specified as a Go duration string (e.g. 4320h), the value must be at least 24 hours.
* `enabled` `(bool: true)` - If set to false, automatic rotations will not be performed. Tracking of encryption counts will continue.

#### Sample payload

```json
{
  "max_operations": 2000000000,
  "interval": "4320h"
}
```

#### Sample request

```shell-session
$ curl \
    --request POST \
    --header "X-Vault-Token: ..." \
    --data @payload.json \
    http://127.0.0.1:8200/v1/sys/rotate/config
```

### Get the auto rotation configuration

| Method | Path                 |
| ------ | -------------------- |
| `GET`  | `/sys/rotate/config` |

#### Sample request

```shell-session
$ curl \
    --request GET \
    --header "X-Vault-Token: ..." \
    http://127.0.0.1:8200/v1/sys/rotate/config
```

#### Sample response

```json
{
  "request_id": "f3d91b4a-69bf-4aaf-b928-df7a5486c130",
  "lease_id": "",
  "lease_duration": 0,
  "renewable": false,
  "data": {
    "max_operations": 2000000000,
    "interval": "4320h",
    "enabled": true
  },
  "warnings": null
}
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.enclaive.cloud/vault/api/system-backend/sys-rotate-config.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
