Struct libp2p_noise::Keypair

pub struct Keypair<T: Zeroize> { /* fields omitted */ }

DH keypair.

Methods

impl Keypair<X25519>

pub fn new() -> Keypair<X25519>

Create a new X25519 keypair.

pub fn from_identity(id_keys: &Keypair) -> Option<AuthenticKeypair<X25519>>

Creates an X25519 Keypair from an identity::Keypair, if possible.

The returned keypair will be associated with the given identity keypair.

Returns None if the given identity keypair cannot be used as an X25519 keypair.

Note: If the identity keypair is already used in the context of other cryptographic protocols outside of Noise, e.g. for signing in the secio protocol, it should be preferred to create a new static X25519 keypair for use in the Noise protocol.

impl<T: Zeroize> Keypair<T>

pub fn public(&self) -> &PublicKey<T>

The public key of the DH keypair.

pub fn secret(&self) -> &SecretKey<T>

The secret key of the DH keypair.

pub fn into_authentic(
    self,
    id_keys: &Keypair
) -> Result<AuthenticKeypair<T>, NoiseError> where
    T: AsRef<[u8]>, 

Turn this DH keypair into a AuthenticKeypair, i.e. a DH keypair that is authentic w.r.t. the given identity keypair, by signing the DH public key.
