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 aservice accountthat hasdomain-wide delegation authorityto impersonate users with thehttps://www.googleapis.com/auth/gmail.settings.basicscope.
For users managing their own identities and keypairs, requests requirehardware key encryptionturned on and configured.
