Before you start configuring this integration, ensure you meet the following prerequisites:

Before you start

Configure Identity and Access Management

Set up the external key service for Google Workspace CSE

Validate and test the integration

Google Workspace Client-Side Encryption

Zone Signing Key - A DNSSEC key used to sign all other zone data (e.g., A, MX, TXT records). It changes more frequently than the KSK.

Key Signing Key - A DNSSEC key used to sign the DNSKEY record set, which includes both the KSK and ZSK. It establishes trust with the parent zone (used in the DNSSEC chain of trust).

Domain Name System Security Extensions - Is a set of protocols that adds cryptographic authentication to DNS, ensuring that DNS responses are not tampered with and come from a legitimate source.

DNSSEC

Bulk Encryption Key - Is a data encryption key used to directly encrypt and decrypt user data. It is typically encrypted (wrapped) by a higher-level key, such as a KEK or PMK, for secure storage and access control.

Futurex Token Key - Wraps all keys stored on the HSM used with PKCS #11.

Is a plugin for OpenSSL 3 that allows OpenSSL to use cryptographic keys stored in PKCS#11-compatible hardware or software security modules (HSMs). Developed by Latchset, it acts as a bridge between OpenSSL and external key providers.

pkcs11-provider

Identity and Access Management — A framework of policies, tools, and processes that ensures the right individuals have the appropriate access to systems, data, and resources. 

Key Encryption Key — A cryptographic key used to encrypt and protect other encryption keys (such as Data Encryption Keys) during storage or transmission. The KEK ensures that the underlying keys remain secure even if stored in a less secure envir

Identity Provider – A service that authenticates users before they can encrypt or access client-side encrypted content.

Key Access Control List Service - A component of an external key service (such as CryptoHub) that communicates with Google Workspace through API to enforce policy control over the users or services accessing encryption keys stored externally.

KACLS

Encrypt, Decrypt, Sign, Verify, Wrap, and Unwrap

EDSVWU

An open-source toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-featured cryptographic library. It is widely used for securing communications and handling cryptographic operations 

OpenSSL

name daemon - The main DNS server daemon for BIND (Berkeley Internet Name Domain). It handles DNS queries, zone transfers, and other DNS server operations.

named

Domain Name System - A hierarchical system that resolves human-readable domain names (e.g., example.com) into IP addresses (e.g., 93.184.216.34) so that devices can locate and communicate with each other on a network.

Authorization framework for secure API access
