Struct Signature

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

Opaque struct representing a LM-OTS signature

Implementations

impl<Mode: LmsOtsMode> Signature<Mode>

pub fn recover_pubkey( &self, id: [u8; 16], q: u32, msg: &[u8], ) -> VerifyingKey<Mode>

Returns a public key candidate for this signature as defined by algorithm 4b of the LMS RFC. The signature will always be valid for the returned public key candidate.

Trait Implementations

impl<Mode: LmsOtsMode> 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: Debug + LmsOtsMode> Debug for Signature<Mode>

where Mode::Hasher: Debug, Mode::PLen: Debug,

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

Formats the value using the given formatter.

impl<Mode: LmsOtsMode> From<Signature<Mode>> for Output<Mode>

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

Converts a Signature into its byte representation

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

Converts to this type from the input type.

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

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

type Repr = GenericArray<u8, <<<Mode as LmsOtsMode>::NLen as Mul<<<Mode as LmsOtsMode>::PLen as Add<UInt<UTerm, B1>>>::Output>>::Output as Add<UInt<UInt<UInt<UTerm, B1>, B0>, B0>>>::Output>

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<'a, Mode: LmsOtsMode> TryFrom<&'a [u8]> for Signature<Mode>

where <Mode::Hasher as OutputSizeUser>::OutputSize: Add<U2>, Sum<<Mode::Hasher as OutputSizeUser>::OutputSize, U2>: ArrayLength<u8>,

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.

impl<Mode: Eq + LmsOtsMode> Eq for Signature<Mode>

where Mode::Hasher: Eq, Mode::PLen: Eq,
