}

A runtime interface for an application’s public key.

Required Associated Constants

const ID: KeyTypeId

An identifier for this application-specific key type.

const CRYPTO_ID: CryptoTypeId

The identifier of the crypto type of this application-specific key type.

Required Associated Types

type Signature: Codec + Debug + MaybeHash + Eq + PartialEq + Clone

The signature that will be generated when signing with the corresponding private key.

Required Methods

fn all() -> Vec<Self>

Returns all public keys for this application in the keystore.

fn generate_pair(seed: Option<Vec<u8>>) -> Self

Generate a public/private pair with an optional seed and store it in the keystore.

The seed needs to be valid utf8.

Returns the generated public key.

fn sign<M>(&self, msg: &M) -> Option<Self::Signature>

where M: AsRef<[u8]>,

Sign the given message with the corresponding private key of this public key.

The private key will be requested from the keystore.

Returns the signature or None if the private key could not be found or some other error occurred.

fn verify<M>(&self, msg: &M, signature: &Self::Signature) -> bool

where M: AsRef<[u8]>,

Verify that the given signature matches the given message using this public key.

fn to_raw_vec(&self) -> Vec<u8>

Returns Self as raw vec.

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.
