Struct EcdhP256 

pub struct EcdhP256;

ECDH over P-256.

Implementations

impl EcdhP256

pub fn public_key_compressed(private_key: &[u8], out: &mut [u8]) -> Result<()>

Compute the public key in SEC1 compressed form (33 bytes).

Interoperates with TLS, COSE, and JOSE, which all prefer compressed points. KeyAgreement::agree accepts either form.

Trait Implementations

SEC1 uncompressed: 0x04 || X || Y.

const PRIVATE_KEY_LEN: usize = 32

Private key (scalar) length in bytes.

const SHARED_SECRET_LEN: usize = 32

Shared secret length in bytes.

fn public_key(private_key: &[u8], out: &mut [u8]) -> Result<()>

Compute the public key for a private key.

fn agree( private_key: &[u8], peer_public_key: &[u8], out: &mut [u8], ) -> Result<()>

Compute the shared secret from our private key and their public key.

impl SelfTest for EcdhP256

fn self_test() -> Result<()>

Run the algorithm’s known-answer test.
