This document shows an example of using the key protect feature to unwrap keys.
Base requirements include that as mentioned in the README.md, as well as the following:
- Access to Key Protect (KP)
- Know the key protect URL - i.e. https://us-south.kms.cloud.ibm.com/
- Have the bluemix instance ID for your KP instance
- Have an apikey to access the unwrap API for your KP instance (for your keys)
- For this example, we will be using crio, therefore requires a cluster with Kubernetes (>= 1.17) with cri-o runtime (>=1.17)
For this example, we will use the direct deployment which is supported. Observer
the file deploy/kp_deploy.yaml, and note the configuration at the bottom of the
file:
apiVersion: v1
kind: Secret
metadata:
name: keyprotect-config
namespace: enc-key-sync
type: Opaque
stringData:
config.json: |
{
"keyprotect-url":"<PLACEHOLDER: i.e. https://us-south.kms.cloud.ibm.com>",
"instance-id": "<PLACEHOLDER: your bluemix instance ID>",
"apikey": "<PLACEHOLDER: apikey-for-accessing-unwrap-api>"
}
This secret encapsulates the configuration required for keyprotect instance, replace the place holder details in this file.
Once that is done, deploy the operator on the cluster with kubectl.
By default, it will install the operator in the enc-key-sync namespace.
$ kubectl apply -f deploy/kp_deploy.yaml
Verify that the daemonset is running by observing the pods in the namespace:
$ kubectl -n enc-key-sync get pods
NAME READY STATUS RESTARTS AGE
enc-key-sync-nt27j 1/1 Running 0 2m50s
As per the example in the README, we will use the same key, but we will wrap it with keyprotect so that it is only accessible by the daemonset and remains encrypted in transit:
Create the private key file on disk
$ cat > my-priv-key.pem <<EOF

create a KP key and then, wrap the the payload above as the plaintext and setting aad as the empty list.
An example would look like this (with the credentials masked):
