Creating Keys

This section describes steps to create an encryption key using the CTE API.

Overview

Keys in a CTE policy must fulfill the following conditions. The keys should:

• Have the CTE Clients group permissions

• Be exportable

• Be non-versioned/versioned

• Be of the type "CBC" / "CBC_CS1"

• Have metadata with the following details:

  {
      "cte": {
          "is_used": <true/false>,
          "cte_versioned": <true/false>,
          "encryption_mode": <"CBC_CS1">,
          "persistent_on_client": <true/false>
      },
      "ownerId": "string",
      "permissions": {
          "ReadKey": [
              "CTE Clients"
          ],
          "ExportKey": [
              "CTE Clients"
          ]
      }
  }
  

CTE supports standard policies.

Keys for Standard Policies

• Standard policies support only non-versioned keys.

• CTE Clients group should have the Read Key and Export Key permissions.

• Standard policies support "CBC_CS1" keys.

  },
  "xts": false
}

Deleting CTE Keys

• A CTE key cannot be deleted if it is being used in a policy.

• The CTE Admins and Key Admins group permissions are required to delete a CTE key.
