Struct Ed448PrivateKey 

pub struct Ed448PrivateKey { /* private fields */ }

Holds a 57-byte Ed448 secret seed used by the in-house signing API.

Implementations

impl Ed448PrivateKey

pub fn from_seed(seed: &[u8; 57]) -> Self

Wraps a 57-byte secret seed as a signing key (RFC 8032 private scalar seed).

Arguments

• seed: 57-byte secret seed (not clamped like X25519).

Returns

Ed448PrivateKey ready to sign messages.

Panics

This function does not panic.

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

Returns the raw 57-byte signing seed.

Returns

Seed octets that were used to construct this private key.

Panics

This function does not panic.

pub fn clear(&mut self)

Clears signing seed bytes in place.

Arguments

• self — Private key whose seed buffer is scrubbed.

Returns

(); all seed bytes are reset to zero.

Panics

This function does not panic.

pub fn verifying_key(&self) -> Ed448PublicKey

Returns the verifying key paired with this signing key.

Returns

Corresponding Ed448PublicKey.

pub fn sign(&self, message: &[u8]) -> [u8; 114]

Signs an arbitrary message (TLS CertificateVerify signs this digest directly).

Arguments

• self: Secret key.
• message: Message bytes to sign (not pre-hashed).

Returns

114-byte Ed448 signature.

Trait Implementations

impl Clone for Ed448PrivateKey

fn clone(&self) -> Ed448PrivateKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ed448PrivateKey

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

Formats the value using the given formatter.

impl Drop for Ed448PrivateKey

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.
