Trait implemented by supported BLS public key types

Required Associated Constants

const ALG_TYPE: BlsCurves

The associated algorithm type

const JWK_CURVE: &'static str

The associated JWK curve name

const JWK_CURVE_OKP: &'static str

The associated JWK curve name (OKP variant)

Required Associated Types

type Buffer: Clone + Debug + PartialEq + Sized + Zeroize

The concrete key representation

type BufferSize: ArrayLength<u8>

The size of the serialized compressed public key

type BufferSizeWide: ArrayLength<u8>

The size of the serialized uncompressed public key

Required Methods

fn from_secret_scalar(secret: &Scalar) -> Self::Buffer

Initialize from the secret scalar

fn from_public_bytes(key: &[u8]) -> Result<Self::Buffer, Error>

Initialize from the compressed bytes

fn with_bytes<O>( buf: &Self::Buffer, alg: Option<KeyAlg>, f: impl FnOnce(&[u8]) -> O, ) -> O

Access the bytes of the public key

fn with_bytes_uncompressed<O>( buf: &Self::Buffer, alg: Option<KeyAlg>, f: impl FnOnce(&[u8]) -> O, ) -> O

Access the coordinates of the public key

Provided Methods

fn get_jwk_curve(_alg: Option<KeyAlg>) -> &'static str

Get the JWK curve for a specific key algorithm

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
