pub struct Secp256k1;

Secp256k1 (a.k.a. k256) Elliptic Curve Digital Signature Algorithm

Trait Implementations

impl Curve for Secp256k1

fn verify( public_key: &VerifyingKey, prehash: &[u8], signature: &Self::Signature, ) -> bool

Verify secp256k1 signature over 32-byte prehash (i.e. output of cryptographic hash function) for given public key.

type PublicKey = VerifyingKey<Secp256k1>

Public key

type Signature = Signature<Secp256k1>

Signature

impl RecoverableCurve for Secp256k1

type RecoveryId = RecoveryId

An additional information required to recover the public key.

fn recover( prehash: &[u8], signature: &Self::Signature, recovery_id: Self::RecoveryId, ) -> Option<Self::PublicKey>

Try to recover public key which signed given message and produced given signature along with a recovery id

impl RecoverableSigner<Secp256k1> for SigningKey

async fn sign_recoverable( &self, prehash: &[u8], ) -> Result<(<Secp256k1 as Curve>::Signature, <Secp256k1 as RecoverableCurve>::RecoveryId), Self::Error>

Sign 32-byte prehash (i.e. output of cryptographic hash function) and return a signature along with recovery id.

If given prehash is of different length, an error will be returned.

impl Signer<Secp256k1> for SigningKey

async fn sign( &self, prehash: &[u8], ) -> Result<<Secp256k1 as Curve>::Signature, Self::Error>

Sign 32-byte prehash (i.e. output of cryptographic hash function).

If given prehash is of different length, an error will be returned.

type Error = Error

An error that can occur during signing.

fn public_key(&self) -> <Secp256k1 as Curve>::PublicKey

Public key of the signer

fn cache_public_key(self) -> CachePublicKey<C, Self>

where Self: Sized,

impl TypedCurve for Secp256k1

const CURVE_TYPE: &str = "secp256k1"

Used as prefix: <CURVE>:...

fn to_base58(bytes: impl AsRef<[u8]>) -> String

Encodes bytes to string as <CURVE>:<base58>

fn parse_base58<const N: usize>( s: impl AsRef<str>, ) -> Result<[u8; N], ParseCurveError>

Decodes bytes from string as <CURVE>:<base58>
