encryptionKey property
Encrypts resources of this workstation configuration using a customer-managed encryption key (CMEK).
If specified, the boot disk of the Compute Engine instance and the persistent disk are encrypted using this encryption key. If this field is not set, the disks are encrypted using a generated key. Customer-managed encryption keys do not protect disk metadata. If the customer-managed encryption key is rotated, when the workstation instance is stopped, the system attempts to recreate the persistent disk with the new version of the key. Be sure to keep older versions of the key until the persistent disk is recreated. Otherwise, data on the persistent disk might be lost. If the encryption key is revoked, the workstation session automatically stops within 7 hours. Immutable after the workstation configuration is created.
Immutable.
