Struct RoomCrypto 

pub struct RoomCrypto { /* private fields */ }

Per-room Megolm crypto: one outbound session (ours) + many inbound (others’).

Implementations

impl RoomCrypto

pub fn new_for_room( db: Db, room_id: String, our_fingerprint: String, ) -> Result<Self>

Create a fresh outbound session and persist it.

pub fn load( db: Db, room_id: String, our_fingerprint: String, ) -> Result<Option<Self>>

Load any persisted sessions for the room. Returns None if no outbound session is stored (meaning we haven’t joined or created it).

pub fn encrypt(&mut self, plaintext: &[u8]) -> Result<(String, Vec<u8>)>

Encrypt a plaintext using our outbound session. Returns (session_id, MegolmMessage bytes).

pub fn decrypt( &mut self, sender_fingerprint: &str, session_id: &str, ciphertext: &[u8], ) -> Result<Vec<u8>>

Decrypt a message from a specific sender.

pub fn add_inbound_session( &mut self, sender_fingerprint: &str, session_key_b64: &str, ) -> Result<()>

Add an inbound session from another member. session_key_b64 is the base64-encoded Megolm SessionKey they shared with us.

pub fn our_session_key_b64(&self) -> String

Get our outbound session key for sharing with new members (base64).

pub fn our_session_id(&self) -> String

pub fn our_fingerprint(&self) -> &str

pub fn room_id(&self) -> &str
