Enum KeyError 

#[non_exhaustive]
pub enum KeyError {
    InvalidPrivateKey,
    InvalidPublicKey,
    NotDidKey,
    NotBase58Btc,
    Multikey(CryptoError),
    WrongCurve {
        codec: KeyCodec,
    },
    NotCompressed {
        got: usize,
    },
    InvalidSignature,
    VerificationFailed,
}

Anything that can go wrong handling a key or a signature.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidPrivateKey

The 32 bytes are not a valid secp256k1 scalar: zero, or at or above the curve order.

InvalidPublicKey

The point bytes are not on the curve, or are otherwise malformed.

NotDidKey

The string did not start with did:key:.

NotBase58Btc

The multibase string was not base58btc, which atproto requires. Other multibase alphabets decode fine but are not interoperable here.

Multikey(CryptoError)

The multibase or multicodec framing did not decode.

WrongCurve

The key decoded, but it is for a curve this crate does not sign with. See the module docs for why there is only one.

Fields

codec: KeyCodec

The codec that was actually present.

NotCompressed

A secp256k1 key in the 65-byte uncompressed form, or some other length.

Fields

got: usize

Length of the key bytes that were present.

InvalidSignature

The 64 bytes are not a well-formed r || s pair.

VerificationFailed

The signature is well-formed but does not match this key and message. A high-S signature lands here too: k256 rejects those on verify.

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.

impl From<CryptoError> for KeyError

fn from(source: CryptoError) -> Self

Converts to this type from the input type.
