Struct k256::schnorr::SigningKey

pub struct SigningKey { /* private fields */ }

Available on crate feature schnorr only.

Taproot Schnorr signing key.

Implementations

impl SigningKey

pub fn random(rng: impl CryptoRng + RngCore) -> Self

Generate a cryptographically random SigningKey.

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

Parse signing key from big endian-encoded bytes.

pub fn to_bytes(&self) -> FieldBytes

Serialize as bytes.

pub fn verifying_key(&self) -> &VerifyingKey

Get the VerifyingKey that corresponds to this signing key.

pub fn try_sign_prehashed(
    &self,
    msg_digest: &[u8; 32],
    aux_rand: &[u8; 32]
) -> Result<Signature>

Compute Schnorr signature.

⚠️ Warning

This is a low-level interface intended only for unusual use cases involving signing pre-hashed messages.

The preferred interfaces are the Signer or RandomizedSigner traits.

Trait Implementations
