Package-level declarations

Types

enum E2EEAlgorithm : Enum<E2EEAlgorithm>

The AES-GCM variants the default manager supports. Determines the required key length.

data class E2EEEvent(val type: E2EEEventType, val name: String, val userId: String?, val trackType: E2EETrackType?, val keyIndex: Int?, val version: Int?, val reason: String?, val keyState: E2EEKeyState?, val encodePerformance: List<E2EETrackPerformance>, val decodePerformance: List<E2EETrackPerformance>)

A state change reported by StreamEncryptionManager, most usefully a decryption failure for a specific participant. Encryption problems are otherwise silent — media simply arrives undecodable — so this is the main signal for surfacing "you are on a different key" in a UI.

E2EEEventListener

fun interface E2EEEventListener

Receives E2EEEvents from StreamEncryptionManager. Invoked on a WebRTC internal thread.

E2EEEventType

enum E2EEEventType : Enum<E2EEEventType>

The kinds of E2EEEvent the native layer reports. UNKNOWN covers constants added by a newer WebRTC build than this SDK was compiled against.

E2EEKeyState

data class E2EEKeyState(val perUserKeys: List<E2EEUserKey>, val sharedKeys: List<E2EESharedKey>)

A snapshot of the keys the manager currently holds. See StreamEncryptionManager.requestKeyState.

E2EEManager

interface E2EEManager

Attaches end-to-end encryption to the media that flows through a call.

E2EESharedKey

data class E2EESharedKey(val keyIndex: Int, val fingerprint: String, val isActive: Boolean)

A key held for every participant. isActive marks the index used for outgoing frames.

E2EETrackPerformance

data class E2EETrackPerformance(val userId: String, val trackType: E2EETrackType?, val codec: String?, val fps: Double, val maxCryptoMs: Double)

Crypto cost for one track, reported while StreamEncryptionManager.enablePerformanceReporting is on.

E2EETrackType

enum E2EETrackType : Enum<E2EETrackType>

The kind of track being encrypted or decrypted, passed to E2EEManager so implementations can key or tag frames per media type.

E2EEUserKey

data class E2EEUserKey(val userId: String, val keyIndex: Int, val fingerprint: String)

A key held for one participant. fingerprint is a digest, not the key material, and is safe to log — it is there so two devices can confirm they agree without exchanging keys.

StreamEncryptionManager

class StreamEncryptionManager : E2EEManager

The SDK's default E2EEManager, backed by WebRTC's framed AES-GCM encryption. Frames are encrypted before they leave the device and decrypted after they arrive, so the SFU forwards media it cannot read.
