Struct LamportSignature 

pub struct LamportSignature { /* private fields */ }

Lamport one-time signature (post-quantum secure).

Private key material is securely zeroized from memory when dropped.

Implementations

impl LamportSignature

pub fn generate() -> Result<Self>

Generate new Lamport key pair.

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

Sign message (ONE TIME ONLY).

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

Verify a Lamport signature (constant-time: no early returns on mismatch).

pub fn is_used(&self) -> bool

Check if key has been used.

pub fn public_key(&self) -> &[u8]

Get public key.

pub fn fingerprint(&self) -> String

Get key fingerprint.

Trait Implementations

impl Drop for LamportSignature

fn drop(&mut self)

Executes the destructor for this type.

impl Zeroize for LamportSignature

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
