VerifyingKey

k256::schnorr

Struct VerifyingKey 

Source 
pub struct VerifyingKey { /* private fields */ }
Expand description

Taproot Schnorr verifying key.

Implementations§

Source§

impl VerifyingKey

Source

pub fn as_affine(&self) -> &AffinePoint

Borrow the inner AffinePoint this type wraps.

Source

pub fn to_bytes(&self) -> FieldBytes

Serialize as bytes.

Source

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.

Source

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

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