Methods

`Abstract` decryptEvent

decryptEvent(event): Promise<IEventDecryptionResult>
Decrypt an event
Parameters
- event: MatrixEvent
  undecrypted event
Returns Promise<IEventDecryptionResult>
promise which resolves once we have finished decrypting. Rejects with an algorithms.DecryptionError if there is a problem decrypting the event.
- Defined in src/crypto/algorithms/base.ts:149

hasKeysForKeyRequest

hasKeysForKeyRequest(keyRequest): Promise<boolean>
Determine if we have the keys necessary to respond to a room key request
Parameters
- keyRequest: IncomingRoomKeyRequest
Returns Promise<boolean>
true if we have the keys and could (theoretically) share them; else false.
- Defined in src/crypto/algorithms/base.ts:175

importRoomKey

importRoomKey(session, opts): Promise<void>
Import a room key
Parameters
- session: IMegolmSessionData
- opts: object
  object
Returns Promise<void>
- Defined in src/crypto/algorithms/base.ts:165

onRoomKeyEvent

onRoomKeyEvent(params): Promise<void>
Handle a key event
Parameters
- params: MatrixEvent
  event key event
Returns Promise<void>
- Defined in src/crypto/algorithms/base.ts:156

`Optional` onRoomKeyWithheldEvent

onRoomKeyWithheldEvent(event): Promise<void>
Parameters
- event: MatrixEvent
Returns Promise<void>
- Defined in src/crypto/algorithms/base.ts:198

retryDecryptionFromSender

retryDecryptionFromSender(senderKey): Promise<boolean>
Retry decrypting all the events from a sender that haven't been decrypted yet.
Parameters
- senderKey: string
  the sender's key
Returns Promise<boolean>
- Defined in src/crypto/algorithms/base.ts:193

`Optional` sendSharedHistoryInboundSessions

sendSharedHistoryInboundSessions(devicesByUser): Promise<void>
Parameters
- devicesByUser: Map<string, DeviceInfo[]>
Returns Promise<void>
- Defined in src/crypto/algorithms/base.ts:199

shareKeysWithDevice

shareKeysWithDevice(keyRequest): void
Send the response to a room key request
Parameters
- keyRequest: IncomingRoomKeyRequest
Returns void
- Defined in src/crypto/algorithms/base.ts:183
