+### End-to-end encryption

-La Suite Meet is fully self-hostable and released under the MIT License, ensuring complete control and flexibility. It's simple to [get started](https://visio.numerique.gouv.fr/) or [request a demo](mailto:visio@numerique.gouv.fr). 
+La Suite Meet supports end-to-end encryption (E2EE) for meetings, so the media server (LiveKit SFU) cannot read audio, video or screen-share content.
+
+#### How it works
+
+- Each encrypted meeting carries a 48-character random passphrase appended to the URL hash (`#…`). The server never sees it; sharing the meeting link shares the key.
+- Frames are encrypted in the browser via LiveKit's Worker + `crypto.subtle` (AES-GCM); only the media payload is encrypted, codec headers stay clear so the SFU can still packetize RTP.
+- The runtime "is this call encrypted?" decision keys off the URL hash, not the database flag — a compromised server cannot fabricate a passphrase that all participants happen to share.
+- The DB flag (`Room.is_encrypted`) is a hint used at room creation time only (so the Create button knows to generate a hash) and to detect link/server inconsistencies.
+
+#### Opt-in by user
+
+End-to-end encryption is a per-user preference. In **Settings → Security**, signed-in users can enable "End-to-end encryption" — from then on every meeting they create is encrypted by default. Joining is unaffected: if a meeting URL has a passphrase, the joining client uses it.
+
+#### Pause / resume for recording and transcription
+
+While encryption is on, the SFU cannot record or transcribe (it has nothing to read). When an admin (or, if no admin is present, the longest-present participant — provided a pause has already been observed in the session) starts a recording or transcription:
+
+1. A confirmation dialog warns that encryption will be paused.
+2. On confirm, an `ENCRYPTION_PAUSED` message is broadcast over a LiveKit reliable data channel. While the sender hasn't yet flipped its own state, that message is itself encrypted — which is the trust anchor: only callers holding the passphrase can produce frames everyone can decrypt.
+3. Each receiver disables E2EE locally and republishes its tracks unencrypted.
+4. Late joiners send an `ENCRYPTION_STATUS_PROBE` so the leader can re-emit the announcement to them.
+5. When **both** recording and transcription stop, the participant who paused broadcasts `ENCRYPTION_RESUMED` and everyone re-enables E2EE with the same URL passphrase.
+
+The pause state is intentionally session-only and never persisted — `Room.is_encrypted` does not flip.
+
+#### Phone / SIP participants
+
+Phone and other external devices can't decrypt our frames. When one joins an encrypted room, the backend webhook detects them, broadcasts a system notice (admins see a snackbar with an "Open settings" CTA), and removes the external participant. The admin can then disable encryption from the Security settings and the user can dial in again.
+
+#### Configuration
+
+```env
+ENCRYPTION_ENABLED=true
+```
+
+Setting `ENCRYPTION_ENABLED=false` disables the user preference toggle entirely; existing encrypted rooms stay encrypted but no new ones can be created.

 This allows you to verify which recordings are in progress, troubleshoot egress issues, and confirm that recordings are being processed correctly.

-## Tuning recording encoding
-
-By default, LiveKit Egress records with the built-in `H264_720P_30` preset: 1280×720 at 30 fps, 3000 kbps H.264 MAIN video and 128 kbps AAC audio. For a one-hour meeting this produces a file of roughly **1.4 GB**, which is often heavier than necessary for talking-head content and screen sharing.
-
-The `RECORDING_ENCODING_*` settings let operators override this preset without modifying the source. Values are passed straight through LiveKit's `EncodingOptions.advanced` to the GStreamer pipeline (`x264enc` for video, `faac` for audio), so there are no hidden conversions — what you set is what the encoder receives.
-
-### How values map to GStreamer
-
-| Setting                               | GStreamer element | Property                           |
-| ------------------------------------- | ----------------- | ---------------------------------- |
-| `RECORDING_ENCODING_WIDTH/HEIGHT`     | capsfilter        | `video/x-raw,width=W,height=H`     |
-| `RECORDING_ENCODING_FRAMERATE`        | capsfilter        | `framerate=F/1`                    |
-| `RECORDING_ENCODING_VIDEO_BITRATE_KBPS` | `x264enc`       | `bitrate=kbps` (kilobits)          |
-| `RECORDING_ENCODING_KEY_FRAME_INTERVAL_S` | `x264enc`     | `key-int-max = interval × fps`     |
-| `RECORDING_ENCODING_AUDIO_BITRATE_KBPS` | `faac`          | `bitrate = kbps × 1000` (bits)     |
-
-The H.264 profile is fixed to MAIN and the x264 `speed-preset` to `veryfast` by LiveKit (real-time constraint) — lowering the framerate is therefore the main lever to save CPU, while lowering the bitrate is the main lever to shrink the output file.
-
-### Reference profiles
-
-Rough 30-minute file-size estimates assume video + audio bitrate multiplied by duration. Actual sizes vary with content (static talking heads compress better than heavy screen motion). Egress CPU figures are indicative, measured on a single Ryzen laptop core saturated by the default preset (= 100 %); scaling is roughly linear with `framerate × bitrate` but the absolute numbers depend on the host hardware.
-
-| Profile                | Resolution | FPS | Video (kbps) | Audio (kbps) | Keyframe (s) | ~ size / 30 min | Egress CPU (vs. default) | Suitable for                                        |

-RECORDING_ENCODING_KEY_FRAME_INTERVAL_S=4.0
-```
-
-### Caveats
-
- **Screen-share readability — think bits/frame, not bitrate**: at 720p, text legibility starts to break down below ~40 kbits/frame (= `bitrate ÷ framerate`). The recommended preset (600 kbps × 15 fps) sits at exactly that threshold, comfortable for talking heads with occasional slide sharing. The same 600 kbps at 30 fps would only deliver 20 kbits/frame and visibly blur dense slides — which is why **lowering framerate is a more screen-share-friendly lever than lowering bitrate**. For deck-heavy or IDE-share meetings, prefer the **Slide-heavy** profile (900 kbps × 15 fps ≈ 60 kbits/frame).
- **Motion handling**: the `veryfast` x264 preset is set by LiveKit and cannot be overridden here. Low-bitrate settings will therefore show more artefacts on fast motion than an offline re-encode with a slower preset would. This is the other reason FPS reduction is the safer tuning lever for meeting recordings.
- **Audio**: AAC at 64 kbps stereo is transparent for voice but starts to compress music noticeably. Keep 128 kbps if you expect music playback in meetings.
- **Codec choice**: H.264 MAIN is hardcoded on purpose. Switching to HEVC or VP9 would increase egress CPU cost 2×–5×, defeating the goal of this tuning.

- * Builds headers for CSRF-protected requests.
- *
- * Two CSRF flows coexist in this addon:
- *
- * 1. Cookie-based (Django default): used by `exchange`, called from the
- *    OAuth success page in a normal browser context. Django's CSRF
- *    middleware has already set the `csrftoken` cookie via the auth
- *    redirect, so we read it from `document.cookie` and echo it back
- *    as `X-CSRFToken`. The middleware verifies the header matches the
- *    cookie. No `csrfToken` argument needed — `getCsrfToken()` handles it.
- *
- * 2. Body-passed token: used by `poll`, called from the Office dialog /
- *    taskpane iframe. Cookie access inside Office iframes is unreliable
- *    across Outlook clients, so we can't depend on `document.cookie`
- *    being populated. Instead, `init` returns the CSRF token in its JSON
- *    response body, and callers pass it explicitly to subsequent calls.
- *    The token still travels as `X-CSRFToken` — only its source differs.
- *
- * The `csrfToken` parameter takes precedence when provided; falls back
- * to the cookie when omitted.

-
-    Implements a three-step flow that lets a third-party add-on (running in an
-    embedded iframe) obtain an access token without exposing it to client-side
-    JavaScript:
-
-    1. /init: the add-on opens a session and receives a short-lived transit
-       token (used to bootstrap the OAuth-style exchange in a dialog) and a
-       CSRF token. The opaque session id is stored in an HttpOnly, Secure,
-       SameSite=None cookie so it can accompany cross-origin polls.
-    2. /poll: the add-on polls until the session transitions from pending to
-       authenticated. On the terminal read, the session payload (access
-       token, token type, expiry, etc.) is returned, the session is evicted
-       server-side, and the session cookie is cleared so the tokens can be
-       retrieved exactly once.
-    3. /exchange: called from the post-login callback page on our own domain,
-       after the user has authenticated in a dialog opened by the addon. The
-       transit token (carried client-side via postMessage + sessionStorage)
-       is redeemed here for the authenticated user's access token, which is
-       stored server-side against the session. Requires an authenticated
-       user — that user is whose access token gets bound to the session.
-
-    /init and /poll authenticate the caller through the session cookie +
-    CSRF token pair alone — no user login is required, since the whole point
-    of the flow is to bootstrap one. /exchange, by contrast, requires an
-    authenticated user and does not use the addonsSid cookie.
