Enum KeyError

pub enum KeyError {
    Base64Error(DecodeError),
    Base64PrivateKey(Error),
    InvalidKeyLength {
        key_type: &'static str,
        expected_length: usize,
        length: usize,
    },
    Signature(SignatureError),
    NonContributoryKey,
}

Error type for failures that may occur when decoding or using a cryptographic key.

Variants

Base64Error(DecodeError)

Failed to correctly decode a public key that was encoded in Base64.

Base64PrivateKey(Error)

Failed to correctly decode a private key that was encoded in Base64.

InvalidKeyLength

The Base64 encoded key does not contain the expected number of bytes.

Fields

key_type: &'static str

The type of key being decoded.

expected_length: usize

The expected length of the key.

length: usize

The actual length of the key.

Signature(SignatureError)

Unable to decompress the curve point r from an Ed25519PublicKey.

For more details, see RFC 8032, Section 5.1.3.

NonContributoryKey

One or more keys lacked contributory behavior in the Diffie-Hellman operation, resulting in an insecure shared secret.

For more details on contributory behavior please refer to the x25519_dalek::SharedSecret::was_contributory() method.

Trait Implementations

impl Debug for KeyError

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

Formats the value using the given formatter.

impl Display for KeyError

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

Formats the value using the given formatter.

impl Error for KeyError

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>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
