Expand description

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

We provide the striaghtfoward implementation which dispatches to the signature.

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

We provide the implementation which dispatches to the signature.

Implementors§

§

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
