Struct SigningKey 

pub struct SigningKey(/* private fields */);

Ed448 signing key (RFC 8032).

Wraps a 57-byte private key. The high bit of the last byte is ignored per RFC 8032 (the “clamping” step is part of signing, not the key storage).

Implementations

impl SigningKey

pub fn from_bytes(bytes: &[u8; 57]) -> Result<Self>

Construct a signing key from raw 57-byte secret bytes.

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

Sign a message. Returns a 114-byte Ed448 signature.

Uses “pure” Ed448 (not Ed448ph) — the message is hashed directly without a prehash separator.

pub fn verifying_key(&self) -> VerifyingKey

Get the corresponding 57-byte public key.

pub fn to_bytes(&self) -> [u8; 57]

Get the 57-byte secret key bytes.

Trait Implementations

impl Clone for SigningKey

fn clone(&self) -> SigningKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SigningKey

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

Formats the value using the given formatter.

impl Drop for SigningKey

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
