Struct VerifyingKey 

pub struct VerifyingKey { /* private fields */ }

Taproot Schnorr verifying key.

Implementations

impl VerifyingKey

pub fn from_bytes(x_bytes: &FieldBytes) -> Result<Self>

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

Errors

Returns an error if a curve point could not be reconstructed from x_bytes.

pub fn from_slice(x_bytes: &[u8]) -> Result<Self>

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

Errors

Returns an error if x_bytes is not 32-bytes long or if a valid curve point could not be reconstructed.

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<()>

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.

Errors

Returns Error if signature is not valid for message.

Trait Implementations
