Struct SigningKey

pub struct SigningKey<P: ParameterSet> { /* private fields */ }

A SigningKey allows signing messages with a fixed parameter set

Implementations

impl<P: ParameterSet> SigningKey<P>

pub fn new(rng: &mut impl CryptoRngCore) -> Self

Create a new SigningKey from a cryptographic random number generator

pub fn try_sign_with_context( &self, msg: &[u8], ctx: &[u8], opt_rand: Option<&[u8]>, ) -> Result<Signature<P>, Error>

Implements [slh-sign] as defined in FIPS-205, using a context string. Context strings must be 255 bytes or less.

Errors

Returns an error if the context string is too long.

pub fn to_bytes(&self) -> Array<u8, P::SkLen>

Serialize the signing key to a new stack-allocated array

This clones the underlying fields

pub fn to_vec(&self) -> Vec<u8>

where P: VerifyingKeyLen,

Serialize the signing key to a new heap-allocated vector

Trait Implementations

impl<P: ParameterSet> AsRef<VerifyingKey<P>> for SigningKey<P>

fn as_ref(&self) -> &VerifyingKey<P>

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

impl<P: Clone + ParameterSet> Clone for SigningKey<P>

where P::N: Clone,

fn clone(&self) -> SigningKey<P>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<P: Debug + ParameterSet> Debug for SigningKey<P>

where P::N: Debug,

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

Formats the value using the given formatter.

impl<P: ParameterSet> KeypairRef for SigningKey<P>

type VerifyingKey = VerifyingKey<P>

Verifying key type for this keypair.

impl<P: PartialEq + ParameterSet> PartialEq for SigningKey<P>

where P::N: PartialEq,

fn eq(&self, other: &SigningKey<P>) -> 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<P: ParameterSet> RandomizedSigner<Signature<P>> for SigningKey<P>

fn try_sign_with_rng( &self, rng: &mut impl CryptoRngCore, msg: &[u8], ) -> Result<Signature<P>, Error>

Attempt to sign the given message, returning a digital signature on success, or an error if something went wrong.

fn sign_with_rng(&self, rng: &mut impl CryptoRngCore, msg: &[u8]) -> S

Sign the given message and return a digital signature

impl<P: ParameterSet> Signer<Signature<P>> for SigningKey<P>

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

Attempt to sign the given message, returning a digital signature on success, or an error if something went wrong.

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

Sign the given message and return a digital signature

impl<P: ParameterSet> TryFrom<&[u8]> for SigningKey<P>

type Error = Error

The type returned in the event of a conversion error.

fn try_from(bytes: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.
