Struct diem_crypto::multi_ed25519::MultiEd25519PublicKey

pub struct MultiEd25519PublicKey { /* fields omitted */ }

Vector of public keys in the multi-key Ed25519 structure along with the threshold.

Implementations

impl MultiEd25519PublicKey

pub fn new(
    public_keys: Vec<Ed25519PublicKey>,
    threshold: u8
) -> Result<Self, CryptoMaterialError>

Construct a new MultiEd25519PublicKey. — Rules — a) threshold cannot be zero. b) public_keys.len() should be equal to or larger than threshold. c) support up to MAX_NUM_OF_KEYS public keys.

pub fn public_keys(&self) -> &Vec<Ed25519PublicKey>

Getter public_keys

pub fn threshold(&self) -> &u8

Getter threshold

pub fn to_bytes(&self) -> Vec<u8>

Serialize a MultiEd25519PublicKey.

Trait Implementations

impl Clone for MultiEd25519PublicKey

fn clone(&self) -> MultiEd25519PublicKey

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MultiEd25519PublicKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MultiEd25519PublicKey

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error> where
    D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Display for MultiEd25519PublicKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&'_ MultiEd25519PrivateKey> for MultiEd25519PublicKey

Implementing From<&PrivateKey<…>> allows to derive a public key in a more elegant fashion.

fn from(private_key: &MultiEd25519PrivateKey) -> Self

Performs the conversion.

impl From<Ed25519PublicKey> for MultiEd25519PublicKey

Convenient method to create a MultiEd25519PublicKey from a single Ed25519PublicKey.

fn from(ed_public_key: Ed25519PublicKey) -> Self

Performs the conversion.

impl Hash for MultiEd25519PublicKey

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Length for MultiEd25519PublicKey

fn length(&self) -> usize

The serialized length of the data

impl PartialEq<MultiEd25519PublicKey> for MultiEd25519PublicKey

fn eq(&self, other: &MultiEd25519PublicKey) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &MultiEd25519PublicKey) -> bool

This method tests for !=.

impl PublicKey for MultiEd25519PublicKey

We deduce PublicKey from this.

type PrivateKeyMaterial = MultiEd25519PrivateKey

We require public / private types to be coupled, i.e. their associated type is each other.

impl Serialize for MultiEd25519PublicKey

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> where
    S: Serializer, 

Serialize this value into the given Serde serializer.

impl TryFrom<&'_ [u8]> for MultiEd25519PublicKey

fn try_from(bytes: &[u8]) -> Result<MultiEd25519PublicKey, CryptoMaterialError>

Deserialize a MultiEd25519PublicKey. This method will also check for key and threshold validity, and will only deserialize keys that are safe against small subgroup attacks.

type Error = CryptoMaterialError

The type returned in the event of a conversion error.

impl ValidCryptoMaterial for MultiEd25519PublicKey

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

Convert the valid crypto material to bytes.

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

The associated signing key type for this verifying key.

type SignatureMaterial = MultiEd25519Signature

The associated signature type for this verifying key.

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.
