Trait diem_crypto::traits::VerifyingKey

pub trait VerifyingKey: PublicKey<PrivateKeyMaterial = Self::SigningKeyMaterial> + ValidCryptoMaterial + Sealed {
    type SigningKeyMaterial: SigningKey<VerifyingKeyMaterial = Self>;
    type SignatureMaterial: Signature<VerifyingKeyMaterial = Self>;
    fn verify_struct_signature<T: CryptoHash + Serialize>(
        &self, 
        message: &T, 
        signature: &Self::SignatureMaterial
    ) -> Result<()> { ... }
    fn batch_verify<T: CryptoHash + Serialize>(
        message: &T, 
        keys_and_signatures: Vec<(Self, Self::SignatureMaterial)>
    ) -> Result<()> { ... }
}

A type family of public keys that are used for signing.

This trait has a requirement on a pub(crate) marker trait meant to specifically limit its implementations to the present crate.

It is linked to a type of the Signature family, which carries the verification implementation.

Associated Types

type SigningKeyMaterial: SigningKey<VerifyingKeyMaterial = Self>

The associated signing key type for this verifying key.

type SignatureMaterial: Signature<VerifyingKeyMaterial = Self>

The associated signature type for this verifying key.

Provided methods

fn verify_struct_signature<T: CryptoHash + Serialize>(
    &self,
    message: &T,
    signature: &Self::SignatureMaterial
) -> Result<()>

We provide the striaghtfoward implementation which dispatches to the signature.

fn batch_verify<T: CryptoHash + Serialize>(
    message: &T,
    keys_and_signatures: Vec<(Self, Self::SignatureMaterial)>
) -> Result<()>

We provide the implementation which dispatches to the signature.

Implementors

impl VerifyingKey for Ed25519PublicKey

type SigningKeyMaterial = Ed25519PrivateKey

type SignatureMaterial = Ed25519Signature

impl VerifyingKey for MultiEd25519PublicKey

We deduce VerifyingKey from pointing to the signature material we get the ability to do pubkey.validate(msg, signature)

type SigningKeyMaterial = MultiEd25519PrivateKey

type SignatureMaterial = MultiEd25519Signature
