Trait KeyAgreement 

pub trait KeyAgreement: Algorithm {
    const PRIVATE_KEY_LEN: usize;
    const PUBLIC_KEY_LEN: usize;
    const SHARED_SECRET_LEN: usize;

    // Required methods
    fn public_key(private_key: &[u8], out: &mut [u8]) -> Result<()>;
    fn agree(
        private_key: &[u8],
        peer_public_key: &[u8],
        out: &mut [u8],
    ) -> Result<()>;
}

A Diffie-Hellman style key agreement scheme.

Required Associated Constants

const PRIVATE_KEY_LEN: usize

Private key (scalar) length in bytes.

const PUBLIC_KEY_LEN: usize

Public key (encoded point) length in bytes.

const SHARED_SECRET_LEN: usize

Shared secret length in bytes.

Required Methods

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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
