Trait Implementations

impl From<Public> for Public

fn from(outer: Public) -> Self

Converts to this type from the input type.

impl RuntimePublic for Public

type Signature = CryptoBytes<sp_core::::sr25519::Signature::{constant#0}, (SignatureTag, Sr25519Tag)>

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

type ProofOfPossession = CryptoBytes<sp_core::::sr25519::Signature::{constant#0}, (SignatureTag, Sr25519Tag)>

The Proof Of Possession the corresponding private key.

fn all(key_type: KeyTypeId) -> Vec<Self>

Returns all public keys for the given key type in the keystore.

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

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

fn sign<M: AsRef<[u8]>>( &self, key_type: KeyTypeId, msg: &M, ) -> Option<Self::Signature>

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

fn verify<M: AsRef<[u8]>>(&self, msg: &M, signature: &Self::Signature) -> bool

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

fn generate_proof_of_possession( &mut self, key_type: KeyTypeId, owner: &[u8], ) -> Option<Self::ProofOfPossession>

Generates the necessary proof(s) usually as a signature or list of signatures, for the corresponding public key to be accepted as legitimate by the network.

fn verify_proof_of_possession( &self, owner: &[u8], proof_of_possession: &Self::ProofOfPossession, ) -> bool

Verifies that the given proof is valid for the corresponding public key. The proof is usually a signature or list of signatures, for the corresponding public key to be accepted by the network. It include attestation of the owner of the public key in the form signing the owner’s identity but might also includes other signatures.

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

Returns Self as raw vec.
