Struct VerifyingKey

pub struct VerifyingKey { /* private fields */ }

Available on crate feature schnorr only.

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) -> GenericArray<u8, <Secp256k1 as Curve>::FieldBytesSize>

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<VerifyingKey, Error>

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

Trait Implementations

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<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VerifyingKey

Available on crate feature serde only.

fn deserialize<D>( deserializer: D, ) -> Result<VerifyingKey, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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

where D: Digest<OutputSize = UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>> + FixedOutput,

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

Verify the signature against the given Digest output.

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 Serialize for VerifyingKey

Available on crate feature serde only.

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

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<Secp256k1>) -> Result<VerifyingKey, Error>

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<Secp256k1>) -> Result<VerifyingKey, Error>

Performs the conversion.

impl Verifier<Signature> for VerifyingKey

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

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