pub enum DecError {
    MacInvalid(MacError),
    Kdf(InvalidLength),
    StreamEnd(StreamCipherError),
    PadError(UnpadError),
}

Error when encrypting message

Most errors can happen when a message has been tampered with.

Variants

MacInvalid(MacError)

Invalid MAC, caused by tampering with the message or using the wrong key

Kdf(InvalidLength)

Rare error for KDF. May be caused by invalid EC instance

StreamEnd(StreamCipherError)

Rare error fo symmetric encryption. May be cause by trying to encrypt too much data

PadError(UnpadError)

Error unpadding, might be caused by sender sending a corrupted message

Trait Implementations

impl Debug for DecError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for DecError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for DecError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)
