Implementations

impl Signature

pub const BYTE_SIZE: usize = 64usize

Size of a Taproot Schnorr signature in bytes.

pub fn to_bytes(&self) -> SignatureBytes

Serialize this signature as bytes.

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl<D> DigestSigner<D, Signature> for SigningKey

where D: Digest + FixedOutput<OutputSize = U32>,

fn try_sign_digest(&self, digest: D) -> Result<Signature>

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

fn sign_digest(&self, digest: D) -> S

Sign the given prehashed message [Digest], returning a signature.

impl<D> DigestVerifier<D, Signature> for VerifyingKey

where D: Digest + FixedOutput<OutputSize = U32>,

fn verify_digest(&self, digest: D, signature: &Signature) -> Result<()>

Verify the signature against the given [Digest] output.

impl From<&Signature> for SignatureBytes

fn from(signature: &Signature) -> SignatureBytes

Converts to this type from the input type.

impl From<Signature> for SignatureBytes

fn from(signature: Signature) -> SignatureBytes

Converts to this type from the input type.

impl PartialEq for Signature

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PrehashSignature for Signature

type Digest = CoreWrapper<CtVariableCoreWrapper<Sha256VarCore, UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>, OidSha256>>

Preferred Digest algorithm to use when computing this signature type.

impl PrehashSigner<Signature> for SigningKey

fn sign_prehash(&self, prehash: &[u8]) -> Result<Signature>

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

impl PrehashVerifier<Signature> for VerifyingKey

fn verify_prehash( &self, prehash: &[u8], signature: &Signature ) -> Result<(), Error>

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

impl<D> RandomizedDigestSigner<D, Signature> for SigningKey

where D: Digest + FixedOutput<OutputSize = U32>,

fn try_sign_digest_with_rng( &self, rng: &mut impl CryptoRngCore, digest: D ) -> Result<Signature>

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

fn sign_digest_with_rng(&self, rng: &mut impl CryptoRngCore, digest: D) -> S
