Struct SignerHandle 

pub struct SignerHandle<K: KeyScheme> { /* private fields */ }

The unlocked handle. Drop wipes the secret.

Cloning a SignerHandle clones the underlying zeroizing buffer — both copies are independently wiped on drop. This is expensive for high-frequency signing; prefer sharing an Arc<SignerHandle<K>> for that case.

Implementations

impl<K: KeyScheme> SignerHandle<K>

pub fn public_key(&self) -> &K::PublicKey

Borrow the derived public key. Cheap (precomputed at unlock time).

pub fn sign(&self, msg: &[u8]) -> K::Signature

Sign a byte message.

pub fn try_sign(&self, msg: &[u8]) -> Result<K::Signature>

Attempt to sign, surfacing any scheme-level errors instead of panicking.

Trait Implementations

impl<K: KeyScheme> Clone for SignerHandle<K>

fn clone(&self) -> Self

Performs copy-assignment from source.

impl<K: KeyScheme> Debug for SignerHandle<K>

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