# Encrypt volume data with NetApp Volume Encryption (NVE)

> Reference to external NetApp documentation for enabling volume encryption (NVE).

Refer to the NetApp ONTAP documentation (

[**docs.netapp.com/us-en/ontap/encryption-at-rest/encrypt-volumes-concept.html**](https://docs.netapp.com/us-en/ontap/encryption-at-rest/encrypt-volumes-concept.html)) to understand and use the NVE capabilities, which include enabling:

* Aggregate-level encryption (

[**docs.netapp.com/us-en/ontap/encryption-at-rest/enable-aggregate-level-encryption-nve-license-task.html**](https://docs.netapp.com/us-en/ontap/encryption-at-rest/enable-aggregate-level-encryption-nve-license-task.html))

* Encryption on new volumes (

[**docs.netapp.com/us-en/ontap/encryption-at-rest/enable-encryption-new-volume-task.html**](https://docs.netapp.com/us-en/ontap/encryption-at-rest/enable-encryption-new-volume-task.html))

* Encryption on existing volumes (

[**docs.netapp.com/us-en/ontap/encryption-at-rest/encrypt-existing-volume-task.html**](https://docs.netapp.com/us-en/ontap/encryption-at-rest/encrypt-existing-volume-task.html))

* Encryption on the SVM root volume (

[**docs.netapp.com/us-en/ontap/encryption-at-rest/configure-nve-svm-root-task.html**](https://docs.netapp.com/us-en/ontap/encryption-at-rest/configure-nve-svm-root-task.html))

* Node root volume encryption (

[**docs.netapp.com/us-en/ontap/encryption-at-rest/enable-root-volume-encryption-task.html**](https://docs.netapp.com/us-en/ontap/encryption-at-rest/enable-root-volume-encryption-task.html))

For all of the preceding encryption operations, ONTAP communicates with the CryptoHub to create and use AES-256 keys through KMIP to encrypt and decrypt volume data as needed.
