Struct solana_libra_nextgen_crypto::bls12381::BLS12381PublicKey

pub struct BLS12381PublicKey(_);

A BLS12-381 public key

Methods

impl BLS12381PublicKey

pub fn to_bytes(&self) -> [u8; 48]

Serializes a BLS12381PublicKey

Methods from Deref<Target = PublicKey>

pub fn verify_g2<H>(&self, sig: &Signature, hash: H) -> bool where
    H: Into<G2Affine>, 

Returns true if the signature matches the element of G2.

pub fn verify<M>(&self, sig: &Signature, msg: M) -> bool where
    M: AsRef<[u8]>, 

Returns true if the signature matches the message.

This is equivalent to verify_g2(sig, hash_g2(msg)).

pub fn encrypt<M>(&self, msg: M) -> Ciphertext where
    M: AsRef<[u8]>, 

Encrypts the message using the OS random number generator.

Uses the OsRng by default. To pass in a custom random number generator, use encrypt_with_rng().

pub fn encrypt_with_rng<R, M>(&self, rng: &mut R, msg: M) -> Ciphertext where
    M: AsRef<[u8]>,
    R: Rng, 

Encrypts the message.

pub fn to_bytes(&self) -> [u8; 48]

Returns a byte string representation of the public key.

Trait Implementations

impl ValidKey for BLS12381PublicKey

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

Convert the valid key to bytes.

fn validate(&self) -> Result<(), CryptoMaterialError>

TryFrom is the source of truth on whether we can build a valid key. => we can use it once we've built, to validate!

impl PublicKey for BLS12381PublicKey

type PrivateKeyMaterial = BLS12381PrivateKey

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

fn length() -> usize

The length of the PublicKey

impl VerifyingKey for BLS12381PublicKey

type SigningKeyMaterial = BLS12381PrivateKey

The associated signing key type for this verifying key.

type SignatureMaterial = BLS12381Signature

The associated signature type for this verifying key.

fn verify_signature(
    &self,
    message: &HashValue,
    signature: &Self::SignatureMaterial
) -> Result<()>

We provide the logical implementation which dispatches to the signature.

fn batch_verify_signatures(
    message: &HashValue,
    keys_and_signatures: Vec<(Self, Self::SignatureMaterial)>
) -> Result<()>

We provide the implementation which dispatches to the signature.
