Below are details about common settings and best practices for\nconfiguring your service.\n\nOperational settings\n--------------------\n\n- The API should only be available over HTTPS with TLS 1.2 or later with a valid\n X.509 certificate.\n\n- The API server should handle [CORS](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS)\n to access Google's authorized end-point: `https://client-side-encryption.google.com`.\n\n- We recommend a maximum latency of 200 ms for 99% of requests.\n\nAuthorization provider settings\n-------------------------------\n\nUse the settings below to validate the Google-issued\n[authorization tokens](/workspace/cse/reference/authorization-tokens) during\nclient-side encryption (CSE):\n\n| Google Workspace application context | JWKS endpoint URL | Authorization token issuer | Authorization token audience |\n|---------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------|------------------------------|\n| **Google Drive and collaborative content creation tools, like Docs and Sheets** | `https://www.googleapis.com/service_accounts/v1/jwk/gsuitecse-tokenissuer-drive@system.gserviceaccount.com` | `gsuitecse-tokenissuer-drive@system.gserviceaccount.com` | `cse-authorization` |\n| **Meet CSE** | `https://www.googleapis.com/service_accounts/v1/jwk/gsuitecse-tokenissuer-meet@system.gserviceaccount.com` | `gsuitecse-tokenissuer-meet@system.gserviceaccount.com` | `cse-authorization` |\n| **Calendar CSE** | `https://www.googleapis.com/service_accounts/v1/jwk/gsuitecse-tokenissuer-calendar@system.gserviceaccount.com` | `gsuitecse-tokenissuer-calendar@system.gserviceaccount.com` | `cse-authorization` |\n| **Gmail CSE** | `https://www.googleapis.com/service_accounts/v1/jwk/gsuitecse-tokenissuer-gmail@system.gserviceaccount.com` | `gsuitecse-tokenissuer-gmail@system.gserviceaccount.com` | `cse-authorization` |\n| **KACLS migration** | `https://www.googleapis.com/service_accounts/v1/jwk/apps-security-cse-kaclscommunication@system.gserviceaccount.com` | `apps-security-cse-kaclscommunication@system.gserviceaccount.com` | `cse-authorization` |\n\nIdentity Provider settings\n--------------------------\n\nThe settings below are required for each non-Google Identity Provider (IdP) your\nservice works with:\n\n- **Method to validate tokens.** Tokens are typically validated by the URL to a JSON Web Key Set (JWKS) file, but could also be the public keys themselves.\n- **Issuer and audience values:** The `iss` (issuer) and `aud` (audience) field values used by each Identity Provider.\n\nPerimeter settings\n------------------\n\nThe perimeter concept in Google Workspace Client-side encryption (CSE) is used\nto provide access control to the encryption keys via the KACLS. The perimeters\nare optional additional checks performed on the authentication and authorization\ntokens within the KACLS.\n\nPerimeters can be used to:\n\n- Only allow users in allowlisted domains to decrypt keys.\n- Blocklist users, such as Google Workspace administrators.\n- Provide advanced restrictions. For example:\n - Time-based restrictions for on-call employees or people on vacation\n - Geolocation restrictions to prevent access from specific locations or networks\n - User role- or type-based access, as asserted by an Identity Provider\n\n| **Note:** The takeout perimeter is used when a Google Workspace customer sends a [Google Takeout](https://support.google.com/a/answer/100458) request with [`takeout_unwrap`](/workspace/cse/reference/takeout_unwrap). The takeout perimeter enables KACLS unwrapping, bypassing the normal Google Workspace ACL, so membership should be restricted to trusted individuals. We recommend that the takeout perimeter use an IdP requiring two-factor authentication (2FA).\n\nVerify your KACLS configuration\n-------------------------------\n\nTo check whether your KACLS is active and configured correctly, send a\n[`status`](/workspace/cse/reference/status) request. Internal self checks,\nlike KMS accessibility or logging system health, can also be performed."]]
