pub struct Signature<Mode: LmsMode> { /* private fields */ }

Opaque struct representing a LMS signature

Trait Implementations

impl<Mode: LmsMode> Clone for Signature<Mode>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Mode: LmsMode> From<Signature<Mode>> for Vec<u8>

where <Mode::OtsMode as LmsOtsMode>::PLen: Add<U1>, <Mode::OtsMode as LmsOtsMode>::NLen: Mul<Sum<<Mode::OtsMode as LmsOtsMode>::PLen, U1>>, Prod<<Mode::OtsMode as LmsOtsMode>::NLen, Sum<<Mode::OtsMode as LmsOtsMode>::PLen, U1>>: Add<U4>, Sum<Prod<<Mode::OtsMode as LmsOtsMode>::NLen, Sum<<Mode::OtsMode as LmsOtsMode>::PLen, U1>>, U4>: ArrayLength<u8>,

fn from(val: Signature<Mode>) -> Self

Converts to this type from the input type.

impl<Mode: LmsMode> PartialEq for Signature<Mode>

fn eq(&self, other: &Self) -> 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<Mode: LmsMode> RandomizedSignerMut<Signature<Mode>> for SigningKey<Mode>

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

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

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

Sign the given message, update the state, and return a digital signature.

impl<Mode: LmsMode> SignatureEncoding for Signature<Mode>

where <Mode::OtsMode as LmsOtsMode>::PLen: Add<U1>, <Mode::OtsMode as LmsOtsMode>::NLen: Mul<Sum<<Mode::OtsMode as LmsOtsMode>::PLen, U1>>, Prod<<Mode::OtsMode as LmsOtsMode>::NLen, Sum<<Mode::OtsMode as LmsOtsMode>::PLen, U1>>: Add<U4>, Sum<Prod<<Mode::OtsMode as LmsOtsMode>::NLen, Sum<<Mode::OtsMode as LmsOtsMode>::PLen, U1>>, U4>: ArrayLength<u8>,

type Repr = Vec<u8>

Byte representation of a signature.

fn to_bytes(&self) -> Self::Repr

Encode signature as its byte representation.

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

Encode signature as a byte vector.

fn encoded_len(&self) -> usize

Get the length of this signature when encoded.

impl<Mode: LmsMode> TryFrom<&[u8]> for Signature<Mode>

Tries to parse a Signature from an exact slice

type Error = LmsDeserializeError

The type returned in the event of a conversion error.

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

Performs the conversion.

impl<Mode: LmsMode> Verifier<Signature<Mode>> for VerifyingKey<Mode>

fn verify(&self, msg: &[u8], signature: &Signature<Mode>) -> Result<(), Error>

Use Self to verify that the provided signature for a given message bytestring is authentic.
