Struct filament_crypto::SigningKey

pub struct SigningKey {
    seed: [u8; 32],
    s: Scalar,
    prefix: [u8; 32],
    vk: VerificationKey,
}

An Ed25519 signing key.

This is also called a secret key by other implementations.

Fields

seed: [u8; 32]

s: Scalar

prefix: [u8; 32]

vk: VerificationKey

Implementations

impl SigningKey

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

Returns the byte encoding of the signing key.

This is the same as .into(), but does not require type inference.

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

View the byte encoding of the signing key.

pub fn verification_key(&self) -> VerificationKey

Obtain the verification key associated with this signing key.

impl SigningKey

pub fn new<R>(rng: R) -> SigningKey

where R: RngCore + CryptoRng,

Generate a new signing key.

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

Create a signature on msg using this key.

Trait Implementations

impl AsRef<[u8]> for SigningKey

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for SigningKey

fn clone(&self) -> SigningKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SigningKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SigningKey

fn deserialize<__D>( __deserializer: __D ) -> Result<SigningKey, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> From<&'a SigningKey> for VerificationKey

fn from(sk: &'a SigningKey) -> VerificationKey

Converts to this type from the input type.

impl From<[u8; 32]> for SigningKey

fn from(seed: [u8; 32]) -> SigningKey

Converts to this type from the input type.

impl From<SerdeHelper> for SigningKey

fn from(helper: SerdeHelper) -> SigningKey

Converts to this type from the input type.

impl Serialize for SigningKey

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&[u8]> for SigningKey

type Error = Error

The type returned in the event of a conversion error.

fn try_from(slice: &[u8]) -> Result<SigningKey, Error>

Performs the conversion.

impl Zeroize for SigningKey

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
