Struct Bls12381ProofOfPossession 

pub struct Bls12381ProofOfPossession { /* private fields */ }

Available on crate feature bls only.

A BLS12-381 proof of possession.

A proof of possession (PoP) proves ownership of the private key corresponding to a public key. This prevents rogue key attacks in aggregate signature schemes.

Implementations

impl Bls12381ProofOfPossession

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

Creates a proof of possession from compressed bytes (96 bytes).

Errors

Returns an error if the bytes length is not 96 bytes or if the proof of possession deserialization fails.

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

Creates a proof of possession 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 proof of possession as compressed bytes (96 bytes).

pub fn to_hex(&self) -> String

Returns the proof of possession as a hex string.

pub fn verify(&self, public_key: &Bls12381PublicKey) -> AptosResult<()>

Verifies this proof of possession against a public key.

Returns Ok(()) if the PoP is valid, or an error if invalid.

Errors

Returns an error if proof of possession verification fails.

Trait Implementations

impl Clone for Bls12381ProofOfPossession

fn clone(&self) -> Bls12381ProofOfPossession

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bls12381ProofOfPossession

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

Formats the value using the given formatter.

impl Display for Bls12381ProofOfPossession

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

impl PartialEq for Bls12381ProofOfPossession

fn eq(&self, other: &Bls12381ProofOfPossession) -> 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.
