Struct linkspace_cryptography::schnorr::SigningKey

pub struct SigningKey { /* private fields */ }

Taproot Schnorr signing key.

Implementations

impl SigningKey

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

Generate a cryptographically random SigningKey.

pub fn from_bytes(bytes: &[u8]) -> Result<SigningKey, Error>

Parse signing key from big endian-encoded bytes.

pub fn to_bytes( &self ) -> GenericArray<u8, <<Secp256k1 as Curve>::UInt as ArrayEncoding>::ByteSize>

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, Error>

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.
