Struct BlsSigner 

pub struct BlsSigner { /* private fields */ }

BLS12-381 signer for Ethereum PoS.

Implementations

impl BlsSigner

pub fn public_key(&self) -> BlsPublicKey

Get the public key.

Trait Implementations

impl Drop for BlsSigner

fn drop(&mut self)

Executes the destructor for this type.

impl KeyPair for BlsSigner

fn generate() -> Result<Self, SignerError>

Generate a new random key pair using OS entropy (CSPRNG).

fn from_bytes(private_key: &[u8]) -> Result<Self, SignerError>

Reconstruct a key pair from raw private key bytes (32 bytes).

fn private_key_bytes(&self) -> Zeroizing<Vec<u8>>

Export the private key as auto-zeroizing bytes. The returned Zeroizing<Vec<u8>> will scrub the memory on drop.

fn from_keypair_bytes(keypair: &[u8]) -> Result<Self, <Self as Signer>::Error>

where Self: Sized,

Reconstruct a key pair from a 64-byte expanded keypair (seed ∥ pubkey). Default impl uses only the first 32 bytes (seed).

fn keypair_bytes(&self) -> Zeroizing<Vec<u8>>

Export the full keypair as private_key ∥ public_key. Default: 32B seed + compressed pubkey.

impl Signer for BlsSigner

fn sign_prehashed(&self, digest: &[u8]) -> Result<BlsSignature, SignerError>

Note: BLS uses hash-to-curve (H2C) internally. This method is identical to sign() — the digest parameter is treated as a raw message, not a pre-computed hash. For consistency with the Signer trait, this is provided as-is.

type Signature = BlsSignature

The signature type produced by this signer.

type Error = SignerError

The error type returned on failure.

fn sign(&self, message: &[u8]) -> Result<BlsSignature, SignerError>

Sign a raw message. The implementation applies chain-specific hashing internally (e.g., Keccak-256 for Ethereum, double-SHA-256 for Bitcoin).

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

Return the public key as bytes (compressed format where applicable).

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

Return the public key in uncompressed format.
