Resource: CseIdentity
The client-side encryption (CSE) configuration for the email address of an authenticated user. Gmail uses CSE configurations to save drafts of client-side encrypted email messages, and to sign and send encrypted email messages.
For administrators managing identities and keypairs for users in their organization, requests require authorization with a service account that has domain-wide delegation authority to impersonate users with the https://www.googleapis.com/auth/gmail.settings.basic scope.
For users managing their own identities and keypairs, requests require hardware key encryption turned on and configured.
