Struct Keypair

pub struct Keypair<E: EngineBLS> {
    pub secret: SecretKey<E>,
    pub public: PublicKey<E>,
}

BLS Keypair

We create Signed messages with a Keypair to avoid recomputing the public key, which usually takes longer than signing when the public key group is G2.

We provide constant-time signing using key splitting.

Fields

secret: SecretKey<E>

public: PublicKey<E>

Implementations

impl<E: EngineBLS> Keypair<E>

pub fn generate<R: Rng>(rng: R) -> Self

Generate a Keypair

impl<E: EngineBLS> Keypair<E>

pub fn into_vartime(&self) -> KeypairVT<E>

Create a representative usable for operations lacking side channel protections.

pub fn sign_with_rng<R: Rng>( &mut self, message: &Message, rng: R, ) -> Signature<E>

Sign a message creating a Signature using a user supplied CSPRNG for the key splitting.

pub fn sign_with_random_seed( &mut self, message: &Message, seed: [u8; 32], ) -> Signature<E>

Sign a message using a Seedabale RNG created from user supplied seed

pub fn sign(&mut self, message: &Message) -> Signature<E>

Sign a message using a Seedabale RNG created from a seed derived from the message and key

pub fn sign_thread_rng(&mut self, message: &Message) -> Signature<E>

Sign a message creating a Signature using the default ThreadRng.

pub fn signed_message(&mut self, message: &Message) -> SignedMessage<E>

Create a SignedMessage using the default ThreadRng.

Trait Implementations

impl<E: EngineBLS> Clone for Keypair<E>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<E: EngineBLS> DoublePublicKeyScheme<E> for Keypair<E>

fn sign(&mut self, message: &Message) -> DoubleSignature<E>

Sign a message using a Seedabale RNG created from a seed derived from the message and key

fn into_public_key_in_signature_group(&self) -> PublicKeyInSignatureGroup<E>

fn into_double_public_key(&self) -> DoublePublicKey<E>

Return a double public object containing public keys both in G1 and G2

impl<E: EngineBLS, H: DynDigest + Default + Clone> ProofOfPossessionGenerator<E, H, DoublePublicKey<E>, NuggetBLSPoP<E>> for Keypair<E>

fn generate_pok(&mut self) -> NuggetBLSPoP<E>

The proof of possession generator is supposed to to produce a schnorr signature or a bls signature using the secret key which it claims to possess. This proves that that the secret key is known.

impl<E: EngineBLS, H: DynDigest + Default + Clone> ProofOfPossessionGenerator<E, H, DoublePublicKey<E>, NuggetBLSnCPPoP<E>> for Keypair<E>

fn generate_pok(&mut self) -> NuggetBLSnCPPoP<E>

The proof of possession generator is supposed to to produce a schnorr signature or a bls signature using the secret key which it claims to possess. This proves that that the secret key is known.

impl<E: EngineBLS, H: DynDigest + Default + Clone> ProofOfPossessionGenerator<E, H, PublicKey<E>, SchnorrPoP<E>> for Keypair<E>

fn generate_pok(&mut self) -> SchnorrPoP<E>

The proof of possession generator is supposed to to produce a schnorr signature or a bls signature using the secret key which it claims to possess. This proves that that the secret key is known.
