Expand description

Error representing a failure during a device to device cryptographic operation.

Variants§

EventError(EventError)

The event that should have been decrypted is malformed.

JsonError(Error)

The received decrypted event couldn’t be deserialized.

SessionCreation(SessionCreationError)

The received room key couldn’t be converted into a valid Megolm session.

SessionExport(SessionExportError)

The room key that should be exported can’t be converted into a m.forwarded_room_key event.

Store(CryptoStoreError)

The storage layer returned an error.

SessionWedged(OwnedUserId, Curve25519PublicKey)

The session with a device has become corrupted.

ReplayedMessage(OwnedUserId, Curve25519PublicKey)

An Olm message got replayed while the Olm ratchet has already moved forward.

MissingSession

Encryption failed because the device does not have a valid Olm session with us.

SessionRecipientCollectionError(SessionRecipientCollectionError)

Encryption failed due to an error collecting the recipient devices.

Withheld(WithheldCode)

Encrypted content is withheld from this device

UnverifiedSenderDevice

Refused to decrypt because the sender was not verified or did not meet the required VerificationLevel.
