Struct P256 

pub struct P256;

P256 (a.k.a. secp256r1) Elliptic Curve Digital Signature Algorithm

Trait Implementations

impl Curve for P256

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

Verify P256 signature over 32-byte prehash (i.e. output of cryptographic hash function) for given public key.

type PublicKey = VerifyingKey<NistP256>

Public key

type Signature = Signature<NistP256>

Signature

impl Signer<P256> for SigningKey

async fn sign( &self, prehash: &[u8], ) -> Result<<P256 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) -> <P256 as Curve>::PublicKey

Public key of the signer

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

where Self: Sized,

impl TypedCurve for P256

const CURVE_TYPE: &str = "p256"

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>
