Struct Keypair

pub struct Keypair(/* private fields */);

An Ed25519 keypair.

(We do not provide a separate “private key only” type.)

See [ed25519_dalek::SigningKey] for more information.

Implementations

impl Keypair

pub fn generate<R: RngCore + CryptoRng>(csprng: &mut R) -> Self

Generate a new random ed25519 keypair.

pub fn from_bytes(bytes: &[u8; 32]) -> Self

Construct an ed25519 keypair from the byte representation of its secret key.

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

Return a reference to the byte representation of the secret key in this keypair.

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

Return to the byte representation of the secret key in this keypair.

pub fn verifying_key(&self) -> PublicKey

Return the public key in this keypair.

pub fn verify(&self, message: &[u8], signature: &Signature) -> Result<(), Error>

Verify a signature generated with this keypair.

pub fn sign(&self, message: &[u8]) -> Signature

Sign a message using this keypair.
