Struct SigningKey 

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

An Ed25519 signing key: the 32-byte seed of RFC 8032 section 5.1.5.

Zeroed on drop.

Implementations

impl SigningKey

pub fn generate() -> Result<Self, Error>

Generate a random signing key from [driver::RngImpl].

pub fn from_bytes(bytes: &[u8; 32]) -> Self

Load a signing key. Every 32-byte string is a valid seed.

pub fn to_bytes(&self) -> [u8; 32]

The seed bytes.

pub fn verifying_key(&self) -> Result<VerifyingKey, Error>

The corresponding verifying key.

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

Sign a message.

Ed25519 signatures are deterministic: signing the same message twice gives the same signature.

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.
