Cloud KMS

Cloud KMS is a cryptographic key management service on GCP. Before using KMS you need to enable it in your project.

$ gcloud services enable cloudkms.googleapis.com


$ KEYRING_NAME=test CRYPTOKEY_NAME=qwiklab
$ gcloud kms keyrings create $KEYRING_NAME --location global

$ gcloud kms keys create $CRYPTOKEY_NAME --location global \
      --keyring $KEYRING_NAME \
      --purpose encryption
