Struct libp2p_core::identity::ed25519::Keypair

pub struct Keypair(_);

An Ed25519 keypair.

Implementations

impl Keypair

pub fn generate() -> Keypair

Generate a new random Ed25519 keypair.

pub fn encode(&self) -> [u8; 64]

Encode the keypair into a byte array by concatenating the bytes of the secret scalar and the compressed public point, an informal standard for encoding Ed25519 keypairs.

pub fn decode(kp: &mut [u8]) -> Result<Keypair, DecodingError>

Decode a keypair from the binary format produced by Keypair::encode, zeroing the input on success.

Note that this binary format is the same as ed25519_dalek’s and ed25519_zebra’s.

pub fn sign(&self, msg: &[u8]) -> Vec<u8>

Sign a message using the private key of this keypair.

pub fn public(&self) -> PublicKey

Get the public key of this keypair.

pub fn secret(&self) -> SecretKey

Get the secret key of this keypair.
