fn sign_schnorr(
&self,
msg: &Message,
sk: &SecretKey
) -> Result<Signature, Error>
&self,
msg: &Message,
sk: &SecretKey
) -> Result<Signature, Error>
Create a Schnorr signature
fn verify_schnorr(
&self,
msg: &Message,
sig: &Signature,
pk: &PublicKey
) -> Result<(), Error>
&self,
msg: &Message,
sig: &Signature,
pk: &PublicKey
) -> Result<(), Error>
Verify a Schnorr signature
fn recover_schnorr(
&self,
msg: &Message,
sig: &Signature
) -> Result<PublicKey, Error>
&self,
msg: &Message,
sig: &Signature
) -> Result<PublicKey, Error>
Retrieves the public key for which sig is a valid signature for msg.
Requires a verify-capable context.
fn generate_keypair<R>(
&self,
rng: &mut R
) -> Result<(SecretKey, PublicKey), Error> where
R: Rng,
&self,
rng: &mut R
) -> Result<(SecretKey, PublicKey), Error> where
R: Rng,
Generates a random keypair. Convenience function for key::SecretKey::new
and key::PublicKey::from_secret_key; call those functions directly for
batch key generation. Requires a signing-capable context.
fn sign(&self, msg: &Message, sk: &SecretKey) -> Result<Signature, Error>
Constructs a signature for msg using the secret key sk and RFC6979 nonce
Requires a signing-capable context.
fn sign_recoverable(
&self,
msg: &Message,
sk: &SecretKey
) -> Result<RecoverableSignature, Error>
&self,
msg: &Message,
sk: &SecretKey
) -> Result<RecoverableSignature, Error>
Constructs a signature for msg using the secret key sk and RFC6979 nonce
Requires a signing-capable context.
fn recover(
&self,
msg: &Message,
sig: &RecoverableSignature
) -> Result<PublicKey, Error>
&self,
msg: &Message,
sig: &RecoverableSignature
) -> Result<PublicKey, Error>
Determines the public key for which sig is a valid signature for
msg. Requires a verify-capable context.
fn verify(
&self,
msg: &Message,
sig: &Signature,
pk: &PublicKey
) -> Result<(), Error>
&self,
msg: &Message,
sig: &Signature,
pk: &PublicKey
) -> Result<(), Error>
Checks that sig is a valid ECDSA signature for msg using the public
key pubkey. Returns Ok(true) on success. Note that this function cannot
be used for Bitcoin consensus checking since there may exist signatures
which OpenSSL would verify but not libsecp256k1, or vice-versa. Requires a
verify-capable context.
