Overview

A key manager is a key management solution (software or dedicated hardware) that enables other ONTAP client modules to securely and persistently store keys for various uses. For example, WAFL uses the key management framework to store and retrieve the volume encryption keys that it uses to encrypt/decrypt data on NVE volumes. A key manager can be configured at both cluster scope and SVM, with one key manager allowed per SVM. The key management framework in ONTAP supports two mutually exclusive modes for persisting keys: external and onboard.

When an SVM is configured with external key management, the keys are stored on up to four key servers that are external to the system.

Once external key management is enabled for an SVM, key servers can be added or removed using the /api/security/key-managers/{uuid}/key-servers endpoint. See [POST /security/key-managers/{uuid}/key-servers] and [DELETE /security/key-managers/{uuid}/key-servers/{server}] for more details.

Setting up external key management dictates that the required certificates for securely communicating with the key server are installed prior to configuring the key manager. To install the required client and server_ca certificates, use the /api/security/certificates/ endpoint.

See [POST /security/certificates], [GET /security/certificates/uuid] and [DELETE /security/certificates/{uuid}] for more details.

When an SVM is configured with the Onboard Key Manager, the keys are stored in ONTAP in wrapped format using a key hierarchy created using the salted hash of the passphrase entered when configuring the Onboard Key Manager. This model fits well for customers who use ONTAP to store their own data.

Examples

Creating an external key manager with 1 key server for a cluster

The example key manager is configured at the cluster-scope with one key server. Note that the UUIDs of the certificates are those that are already installed at the cluster-scope. Note the return_records=true query parameter is used to obtain the newly created key manager configuration

# The API:
POST /api/security/key-managers

# The call:
curl -X POST 'https://<mgmt-ip>/api/security/key-managers?return_records=true' -H 'accept: application/hal+json' -d "{ \"external\": { \"client_certificate\": { \"uuid\": \"5fb1701a-d922-11e8-bfe8-005056bb017d\" }, \"server_ca_certificates\": [ { \"uuid\": \"827d7d31-d6c8-11e8-b5bf-005056bb017d\" }],\"servers\": [ { \"server\": \"10.225.89.33:5696\" } ] } }"

}

Creating an external key manager with 1 primary key server and 2 secondary key servers for a cluster

The example key manager is configured at the cluster-scope with one key server and two secondary key servers.
