    UnknownMessageIndex(u32, u32),
}

Expand description

Error type for Megolm-based decryption failuers.

Variants

`Signature(SignatureError)`

The signature on the message was invalid.

`InvalidMAC(MacError)`

The message authentication code of the message was invalid.

`InvalidPadding(UnpadError)`

The ciphertext of the message isn’t padded correctly.

`UnknownMessageIndex(u32, u32)`

The session is missing the correct message key to decrypt the message, The Session has been ratcheted forwards and the message key isn’t available anymore.
