feat: add end-to-end encryption support - #68

Conversation
145.17.0 is the first stable release carrying the framed AES-GCM E2EE work (GetStream/webrtc#110), which previously shipped only as the 145.16.0 pre-release. The bindings are identical between the two, so the E2EE bridge needed no changes: the Android AAR's classes.jar has the same SHA-256 and RTCEncryptionManager.h is unchanged. The only functional delta is in the audio receive path, where clearing a frame transformer now reaches the media channel instead of being dropped (or hitting a DCHECK); nothing we call exercises that path today. Android resolves from Maven Central now that the version is a release rather than a snapshot. iOS goes back to depending on the StreamWebRTC pod. That pod is published to CocoaPods trunk for this version, and the trunk podspec's source is the same stream-video-swift-webrtc release asset the podspec was downloading by hand, so dropping the vendoring block and third_party/ changes nothing about what gets linked. Also drops the .gitignore entry for the download stamp the block wrote.

- Line 71: Update the disposal flow around the manager lookup so the manager
remains in the managers registry while setObserver(null) and dispose() execute.
Remove the entry only after both native cleanup calls succeed, preserving failed
entries for later dispose() retries and disposeAll() cleanup.

Both bridges narrowed keyIndex with a truncating conversion
(ReadableMap.getInt on Android, NSNumber.intValue on iOS) and left the
range check to the native binding, which only sees the result. Any
fractional value in (-1, 1) therefore landed silently on slot 0 rather
than being rejected, so removeSharedKey(-0.5) removed a live key; NaN
did the same, since it converts to 0 in both languages.
Validate on the double, before narrowing, for every key operation. NaN
fails the integrality comparison and the 0-255 range check covers both
infinities. Rejections reuse the existing {error} result, with the
messages naming the accepted range so a present-but-invalid index no
longer reports as a missing one.
The JS surface documents the range but does not enforce it, which makes
the bridge the trust boundary here.
dispose() removed the handle from the registry before calling setObserver(null) and dispose() on it, so a throwing native cleanup dropped the only reference to the manager: the C++ object leaked, and neither a retried dispose() nor disposeAll() on teardown could still reach it. Deregister only once both native calls succeed, which is also what the iOS bridge already did.
The xcframework is staged under XCFrameworkIntermediates by its owning pod, which went back to StreamWebRTC when the podspec returned to the pod dependency. The path had been left pointing at the vendoring-era stream-react-native-webrtc directory. CocoaPods regenerates this block, and both CI workflows run pod install before building, so this only keeps the tracked file consistent with what the current podspec produces.

changed the title
dispose() marked the manager disposed from a finally block, so a native cleanup failure still flipped the flag and every later dispose() returned early. That defeats the native registries, which deliberately keep a manager registered when its cleanup throws so the call can be retried. The flag and the listener teardown now run only after the native dispose succeeds. The event subscription stays attached on failure, which is correct: the manager still exists natively and can still emit.
Both bridges range-checked the track type only after truncating it: Android compared the result of ReadableMap.getInt, iOS range-checked [value integerValue] and then forwarded the original NSNumber. A fractional or non-finite value therefore landed on a valid enum entry instead of being rejected -- -0.5 and NaN both became AUDIO, 1.5 became VIDEO. Silently selecting audio is the misgrouping the comment above the parser warns about: a screen-share-audio track would join the microphone and share its replay window. Both now validate the double before narrowing, matching the key-index helper -- the floor/trunc comparison rejects NaN and the range check covers both infinities.

💡 Overview Adds end-to-end encryption to the React Native SDK. Encryption runs natively in @stream-io/react-native-webrtc, using the same wire format as the web and iOS SDKs, so encrypted calls interoperate across platforms. - EncryptionManager — native-backed implementation of the core E2EEManager interface, API-compatible with the web manager. - StreamVideoRN.setRingingCallLifecycleHooks() — ringing calls are joined by the SDK, not by app code, so there is no moment where the app can attach a manager before the join. These hooks are that moment, on every ringing path. - Dogfood: passphrase entry, lock badge, live re-keying, key-mismatch warning. 📝 Implementation notes - Call.ts: globalThis.streamRNVideoSDK bridge plus cancellation checks reusing leaveGeneration. No new Call fields; web and non-ringing calls are untouched. - Setup failure or the 5s timeout aborts the join and ends the ringing flow. Joining unencrypted on a call the user believes is private is the worse outcome. - One Call is one call flow — discard it after leave/cancel/failed join. Documented contract, not an enforced ban; inherited reuse behaviour and tests are untouched. - dispose() is mandatory on RN (no native detach, closing peer connections doesn't release it), and gated on teardown succeeding. webrtc PR: GetStream/react-native-webrtc#68 docs PR: GetStream/docs-content#1586 🎫 Ticket: https://linear.app/stream/issue/RN-434/ <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Added React Native end-to-end encryption with AES-GCM key management and status handling. - Added encryption key entry, mismatch notifications, and an encryption indicator during calls. - Encrypted deep links now preserve and apply meeting keys securely. - Added configurable ringing-call lifecycle hooks for call preparation and cleanup. - **Bug Fixes** - Improved cancellation and cleanup when calls are left during joining. - Failed push-call joins now correctly report failure to the calling platform. - **Documentation** - Added guidance and testing documentation for React Native encryption and sample-app workflows. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: GitHub Actions Bot <> Co-authored-by: Gabriel Donadel Dall'Agnol <donadeldev@gmail.com> Co-authored-by: Oliver Lazoroski <oliver.lazoroski@gmail.com>

Follow-ups to the review of #68. - `getTrackById()` now returns the track wrapper the observer keeps. Before, it used `pc.getReceivers()`, which disposes the wrappers from its previous call and detaches their sinks. That broke the recorder when E2EE `decrypt()` or `receiver.getStats()` ran on the same peer connection. Android only. - E2EE event forwarding on Android now catches exceptions and drops the event, so a bad event cannot crash the app. - The two "dispose E2EE managers first" comments no longer read as an ordering requirement. Dispose order does not matter for safety. - `encrypt()` docs say to attach before the sender has a track or is negotiated to send. Tested on dogfood: loopback recording keeps video while receivers are enumerated mid-recording, and E2EE meeting join, leave, rejoin, wrong-key, and bundle reload all pass on both platforms. 🎫 Ticket: https://linear.app/stream/issue/RN-434 <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Prevented failures while processing encryption events from disrupting event delivery; events that cannot be prepared are dropped safely. * Improved remote track lookup consistency. * **Documentation** * Clarified that encryption must be attached before a sender has a track or is negotiated to send; frames sent beforehand are unencrypted. * Clarified encryption manager cleanup behavior during app reloads. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
