```
k3s secrets-encrypt reencrypt --force --skip
```
```
### Secrets Encryption Status
The secrets-encrypt tool includes a `status` command that displays information about the current status of secrets encryption on the node.
An example of the command on a single-server node:
```
$ k3s secrets-encrypt status
Encryption Status: Enabled
Current Rotation Stage: start
Server Encryption Hashes: All hashes match
Active Key Type Name
------ -------- ----
* AES-CBC aescbckey
```
Another example on HA cluster, after rotating the keys, but before restarting the servers:
```
$ k3s secrets-encrypt status
Encryption Status: Enabled
Current Rotation Stage: rotate
Server Encryption Hashes: hash does not match between node-1 and node-2
Active Key Type Name
------ -------- ----
* AES-CBC aescbckey-2021-12-10T22:54:38Z
AES-CBC aescbckey
```
Details on each section are as followed:
- __Encryption Status__: Displayed whether secrets encryption is disabled or enabled on the node
- __Current Rotation Stage__: Indicates the current rotation stage on the node.
Stages are: `start`, `prepare`, `rotate`, `reencrypt_request`, `reencrypt_active`, `reencrypt_finished`
- __Server Encryption Hashes__: Useful for HA clusters, this indicates whether all server are on the same stage with their local files. This can be used to identify whether a restart of servers is required before proceeding to the next stage. In the HA example above, node-1 and node-2 different hashes, indicating that they currently do not have the same encryption configuration. Restarting the servers will sync up their configuration.
- __Key Table__: Summarizes information about the secrets encryption keys found on the node.
* __Active__: The "*" indicates which, if any, of the keys are currently used for secrets encryption. An active key is used by kubernetes to encrypt any new secrets.
* __Key Type__: All keys using this tool are `AES-CBC` type. See more info [here.](https://kubernetes.io/docs/tasks/administer-cluster/encrypt-data/#providers)
* __Name__: Name of the encryption key.
