Enum OpenError 

pub enum OpenError {
    Truncated,
    InvalidCiphertext,
}

crypto_box512 can fail while opening for reasons beyond a wrong key.

Variants

Truncated

sealed is shorter than a KEM ciphertext plus a secretstream header and tag (304 bytes) - too short to have ever been produced by seal.

InvalidCiphertext

Any late-stage failure: wrong secret key, a tampered KEM prefix/header/ciphertext/tag, or a recovered seed whose bit length isn’t exactly SEED_BITS - deliberately collapsed, see the module doc’s “Error collapsing” section.

Trait Implementations

impl Debug for OpenError

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

Formats the value using the given formatter.

impl Display for OpenError

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

Formats the value using the given formatter.

impl Error for OpenError

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>)
