Trait VerifyingKey

pub trait VerifyingKey:

    + ValidCryptoMaterial
    + Sealed {
    type SigningKeyMaterial: SigningKey<VerifyingKeyMaterial = Self>;

    fn verify_struct_signature<T: CryptoHash + Serialize>(
        &self,
        message: &T,
        signature: &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.

Required 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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl VerifyingKey for BLSPublicKey

type SignatureMaterial = BLSSignature

type SigningKeyMaterial = BLSPrivateKey

impl VerifyingKey for Ed25519PublicKey

type SignatureMaterial = Ed25519Signature

type SigningKeyMaterial = Ed25519PrivateKey

impl VerifyingKey for MultiBLSPublicKey

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

type SignatureMaterial = MultiBLSSignature

type SigningKeyMaterial = MultiBLSPrivateKey

impl VerifyingKey for MultiEd25519PublicKey

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

type SignatureMaterial = MultiEd25519Signature

type SigningKeyMaterial = MultiEd25519PrivateKey
