Reason code for a decryption failure
Variants§
MalformedEncryptedEvent
The m.room.encrypted
event that should have been decrypted is
malformed in some way (e.g. unsupported algorithm, missing fields,
unknown megolm message type).
MissingMegolmSession
Decryption failed because we’re missing the megolm session that was used to encrypt the event.
TODO: support withheld codes?
UnknownMegolmMessageIndex
Decryption failed because, while we have the megolm session that was used to encrypt the message, it is ratcheted too far forward.
MegolmDecryptionFailure
We found the Megolm session, but were unable to decrypt the event using that session for some reason (e.g. incorrect MAC).
This represents all vodozemac::megolm::DecryptionError
s, except
UnknownMessageIndex
, which is represented as
UnknownMegolmMessageIndex
.
PayloadDeserializationFailure
The event could not be deserialized after decryption.
MismatchedIdentityKeys
Decryption failed because of a mismatch between the identity keys of the device we received the room key from and the identity keys recorded in the plaintext of the room key to-device message.
SenderIdentityNotTrusted(VerificationLevel)
An encrypted message wasn’t decrypted, because the sender’s
cross-signing identity did not satisfy the requested
TrustRequirement
.
Implementations§
source§impl UnableToDecryptReason
impl UnableToDecryptReason
sourcepub fn is_missing_room_key(&self) -> bool
pub fn is_missing_room_key(&self) -> bool
Returns true if this UTD is due to a missing room key (and hence might resolve itself if we wait a bit.)
