To use Google Workspace Client-side encryption (CSE), you first need to set up an external key service. You can use one of Google's partners, listed below, or build your own key service using the Google CSE API.
Google's key service partners provide tools that meet Google’s specifications and provide both key management and access control capabilities. Your partner holds the key to decode encrypted files, and Google can't access or decipher these files without this key.
When you set up your key service, you'll also create your access control list (ACL)—that is, the users, groups, or domains that you want to have view and edit access to encrypted files.
Set up your external key service with a partner
- Sign up with one of Google's partner encryption key services: FlowCrypt, Fortanix FutureX, Stormshield, Thales, or Virtru.
- Follow the key service's instructions to set up your encryption keys and key ACL.
Your key service will give you a URL to access their service. You'll use this URL to connect Google Workspace to your external key service.
After you set up your external key service, you need to connect Google Workspace to the service.
