Struct Falcon1024Signer 

pub struct Falcon1024Signer { /* private fields */ }

Falcon-1024 signer (lattice-based, ~NIST level 5).

Implementations

impl Falcon1024Signer

pub fn from_seed(seed: &[u8; 32]) -> Result<Self, CryptoError>

Create a signer from a 32-byte seed.

Note: Falcon-1024 keygen is expensive (~100ms on first call; ~10ms on cached re-derivation).

pub fn from_keys(sk: FalconPrivateKey, pk: FalconPublicKey) -> Self

Create from an existing private/public key pair.

pub fn sign(&self, message: &[u8]) -> Result<Vec<u8>, CryptoError>

Sign a message. Returns a ~1280-byte Falcon-1024 signature.

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

Verify a signature against this signer’s public key.

pub fn verify_with_pubkey( pubkey: &[u8], message: &[u8], signature: &[u8], ) -> bool

Verify a signature against an arbitrary Falcon-1024 public key.

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

Get the 1793-byte Falcon-1024 public key.
