Struct VerifyingKey

pub struct VerifyingKey { /* private fields */ }

Taproot Schnorr verifying key.

Implementations

impl VerifyingKey

pub fn as_affine(&self) -> &AffinePoint

Borrow the inner AffinePoint this type wraps.

pub fn to_bytes(&self) -> FieldBytes

Serialize as bytes.

pub fn verify_raw( &self, message: &[u8], signature: &Signature, ) -> Result<(), Error>

Compute Schnorr signature.

⚠️ Warning

This is a low-level interface intended only for unusual use cases involving verifying pre-hashed messages, or “raw” messages where the message is not hashed at all prior to being used to generate the Schnorr signature.

The preferred interfaces are the DigestVerifier or PrehashVerifier traits.

pub fn from_bytes(bytes: &[u8]) -> Result<Self>

Parse verifying key from big endian-encoded x-coordinate.

Trait Implementations

impl AsRef<VerifyingKey> for SigningKey

fn as_ref(&self) -> &VerifyingKey

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

impl Clone for VerifyingKey

fn clone(&self) -> VerifyingKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VerifyingKey

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

Formats the value using the given formatter.

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<&VerifyingKey> for AffinePoint

fn from(vk: &VerifyingKey) -> AffinePoint

Converts to this type from the input type.

impl From<&VerifyingKey> for PublicKey

fn from(vk: &VerifyingKey) -> PublicKey

Converts to this type from the input type.

impl From<VerifyingKey> for AffinePoint

fn from(vk: VerifyingKey) -> AffinePoint

Converts to this type from the input type.

impl From<VerifyingKey> for PublicKey

fn from(vk: VerifyingKey) -> PublicKey

Converts to this type from the input type.

impl PartialEq for VerifyingKey

fn eq(&self, other: &VerifyingKey) -> 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 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 TryFrom<&PublicKey<Secp256k1>> for VerifyingKey

type Error = Error

The type returned in the event of a conversion error.

fn try_from(public_key: &PublicKey) -> Result<VerifyingKey>

Performs the conversion.

impl TryFrom<PublicKey<Secp256k1>> for VerifyingKey

type Error = Error

The type returned in the event of a conversion error.

fn try_from(public_key: PublicKey) -> Result<VerifyingKey>

Performs the conversion.

impl Verifier<Signature> for VerifyingKey

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

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