Google announces Client-side Encryption (CSE) for Gmail

[ 更新于 2023 年 3 月 6 日 ]

Google has announced the launch of Client-side Encryption (CSE) for Gmail. The feature is currently available to all Google Workspace users (Google Workspace Enterprise Plus, Education Plus, or Education Standard, etc.), but not yet available for Personal Workspace plans or Google accounts.

Google states that with this feature, users’ emails and meeting activities will be encrypted before they reach Google servers. The CSE feature is disabled by default, and Workspace administrators need to enable it. Once enabled, users can add CSE to any email in Gmail by clicking on the lock icon to the right of the “To” field and opening the “Extra Encryption” option. The composition panel will turn blue and may display “New encrypted email”; in the calendar, click the shield icon next to the activity title to add “Extra Encryption” to the description, attachment, and Google Meet call.

Google has previously enabled Client-side Encryption (CSE) for Google Drive, Docs, Slides, Sheets, Meet, and Calendar.
