Struct Bls12381PublicKey 

pub struct Bls12381PublicKey { /* private fields */ }

Available on crate feature bls only.

A BLS12-381 public key.

Implementations

impl Bls12381PublicKey

pub fn from_bytes(bytes: &[u8]) -> AptosResult<Self>

Creates a public key from compressed bytes (48 bytes).

Errors

Returns an error if the bytes length is not 48 bytes or if the key deserialization fails.

pub fn from_hex(hex_str: &str) -> AptosResult<Self>

Creates a public key from a hex string.

Errors

Returns an error if hex decoding fails or if the resulting bytes are invalid.

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

Returns the public key as compressed bytes (48 bytes).

pub fn to_hex(&self) -> String

Returns the public key as a hex string.

pub fn verify( &self, message: &[u8], signature: &Bls12381Signature, ) -> AptosResult<()>

Verifies a signature against a message.

Errors

Returns an error if signature verification fails.

impl Bls12381PublicKey

pub fn aggregate( public_keys: &[&Bls12381PublicKey], ) -> AptosResult<Bls12381PublicKey>

Aggregates multiple public keys into a single aggregated public key.

The aggregated public key can be used to verify an aggregated signature.

WARNING: This assumes all public keys have had their proofs-of-possession verified.

Errors

Returns an error if the list of public keys is empty or if aggregation fails.

Trait Implementations

impl Clone for Bls12381PublicKey

fn clone(&self) -> Bls12381PublicKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bls12381PublicKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Bls12381PublicKey

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Bls12381PublicKey

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

Formats the value using the given formatter.

impl PartialEq for Bls12381PublicKey

fn eq(&self, other: &Bls12381PublicKey) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PublicKey for Bls12381PublicKey

fn from_bytes(bytes: &[u8]) -> AptosResult<Self>

Creates a public key from compressed bytes (48 bytes).

Errors

Returns an error if the bytes length is not 48 bytes or if the key deserialization fails.

const LENGTH: usize = BLS12381_PUBLIC_KEY_LENGTH

The length of the public key in bytes.

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

Returns the public key as bytes.

fn to_hex(&self) -> String

Returns the public key as a hex string with 0x prefix.

impl Serialize for Bls12381PublicKey

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Verifier for Bls12381PublicKey

fn verify( &self, message: &[u8], signature: &Bls12381Signature, ) -> AptosResult<()>

Verifies a signature against a message.

Errors

Returns an error if signature verification fails.

type Signature = Bls12381Signature

The signature type this verifier can check.
