Enum CombinedKey 

pub enum CombinedKey {
    Secp256k1(SigningKey<Secp256k1>),
    Ed25519(SigningKey),
}
Expand description

A standard implementation of the EnrKey trait used to sign and modify ENR records. The variants here represent the currently supported in-built signing schemes.

Variants§

§

Secp256k1(SigningKey<Secp256k1>)

An secp256k1 keypair.

§

Ed25519(SigningKey)

An Ed25519 keypair.

Implementations§

§

impl CombinedKey

pub fn generate_secp256k1() -> CombinedKey

Generates a new secp256k1 key.

pub fn generate_ed25519() -> CombinedKey

Generates a new ed25510 key.

pub fn secp256k1_from_bytes(bytes: &mut [u8]) -> Result<CombinedKey, Error>

Imports a secp256k1 from raw bytes in any format.

pub fn ed25519_from_bytes(bytes: &mut [u8]) -> Result<CombinedKey, Error>

Imports an ed25519 key from raw 32 bytes.

pub fn encode(&self) -> Vec<u8> ⓘ

Encodes the CombinedKey into compressed (where possible) bytes.

Trait Implementations§

§

impl EnrKey for CombinedKey

§

fn sign_v4(&self, msg: &[u8]) -> Result<Vec<u8>, SigningError>

Performs ENR-specific signing.

Note: that this library supports a number of signing algorithms. The ENR specification currently lists the v4 identity scheme which requires the secp256k1 signing algorithm. Using secp256k1 keys follow the v4 identity scheme, using other types do not, although they are supported.

§

fn public(&self) -> <CombinedKey as EnrKey>::PublicKey

Returns the public key associated with the private key.

§

fn enr_to_public( content: &BTreeMap<Vec<u8>, Bytes>, ) -> Result<<CombinedKey as EnrKey>::PublicKey, Error>

Decodes the raw bytes of an ENR’s content into a public key if possible.

§

type PublicKey = CombinedPublicKey

§

impl From<SigningKey<Secp256k1>> for CombinedKey

§

fn from(secret_key: SigningKey<Secp256k1>) -> CombinedKey

Converts to this type from the input type.
§

impl From<SigningKey> for CombinedKey

§

fn from(keypair: SigningKey) -> CombinedKey

Converts to this type from the input type.
