# `/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"

## Get the Auto Rotation Configuration

| Method | Path                 |
