Struct SigningKey 

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

A secret key for EdDSA (Ed25519) signature verification over Curve25519.

Implementations

impl SigningKey

pub fn new() -> SigningKey

Generates a new random signing key using the OS random number generator.

This is cryptographically secure as long as rand::rng remains so.

pub fn with_rng<R>(rng: &mut R) -> SigningKey

where R: CryptoRng + RngCore,

Generates a new secret key using RNG.

pub fn public_key(&self) -> PublicKey

Gets the corresponding public key for this secret key.

pub fn sign(&self, message: Word) -> Signature

Signs a message (Word) with this secret key.

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<(), Error>

Formats the value using the given formatter.

impl Deserializable for SigningKey

fn read_from<R>(source: &mut R) -> Result<SigningKey, DeserializationError>

where R: ByteReader,

Reads a sequence of bytes from the provided source, attempts to deserialize these bytes into Self, and returns the result.

fn min_serialized_size() -> usize

Returns the minimum serialized size for one instance of this type.

fn read_from_bytes(bytes: &[u8]) -> Result<Self, DeserializationError>

Attempts to deserialize the provided bytes into Self and returns the result.

fn read_from_bytes_with_budget( bytes: &[u8], budget: usize, ) -> Result<Self, DeserializationError>

Deserializes Self from bytes with a byte budget limit.

impl Display for SigningKey

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

Formats the value using the given formatter.

impl From<SecretKey> for SigningKey

fn from(secret_key: SecretKey) -> SigningKey

Converts to this type from the input type.

impl PartialEq for SigningKey

fn eq(&self, other: &SigningKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serializable for SigningKey

fn write_into<W>(&self, target: &mut W)

where W: ByteWriter,

Serializes self into bytes and writes these bytes into the target.

fn to_bytes(&self) -> Vec<u8>

Serializes self into a vector of bytes.

fn get_size_hint(&self) -> usize

Returns an estimate of how many bytes are needed to represent self.
