Struct PublicKey 

pub struct PublicKey { /* private fields */ }

P-256 (secp256r1) ECDSA public key.

Supports signature verification and ECDH key agreement.

Verification

use crypto::p256::PrivateKey;

let key = PrivateKey::generate().unwrap();
let signature = key.sign(b"message").unwrap();
assert!(key.public_key().verify(b"message", &signature).is_ok());

Implementations

impl PublicKey

pub fn from_bytes(key: &[u8]) -> Result<PublicKey, EllipticCurveError>

pub fn from_x_y( x_bytes: &[u8; 32], y_bytes: &[u8; 32], ) -> Result<PublicKey, EllipticCurveError>

Build a public key from raw affine x and y coordinates (both big-endian, 32 bytes each). Returns InvalidKey if the coordinates are not a valid point on the P-256 curve.

This is useful when importing keys from formats like JWK where x and y are available directly.

pub fn verify( &self, message: &[u8], signature: &[u8; 64], ) -> Result<(), EllipticCurveError>

pub fn to_bytes(&self) -> [u8; 65]

pub fn x_y(&self) -> ([u8; 32], [u8; 32])

Returns the X and Y points as big-endian arrays.
