Struct KeypairVT

pub struct KeypairVT<E: EngineBLS> {
    pub secret: SecretKeyVT<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 G2.2

We provide constant-time signing using key splitting.

Fields

secret: SecretKeyVT<E>

public: PublicKey<E>

Implementations

impl<E: EngineBLS> KeypairVT<E>

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

Generate a Keypair

impl<E: EngineBLS> KeypairVT<E>

pub fn into_split<R: Rng>(&self, rng: R) -> Keypair<E>

Convert into a SecretKey applying side channel protections.

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

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

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

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