pub fn generate_keypair<R>(
&self,

) -> 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.
pub fn sign(&self, msg: &Message, sk: &SecretKey) -> Result<Signature, Error>
pub 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.
pub fn sign_recoverable(
&self,
msg: &Message,
sk: &SecretKey
) -> Result<RecoverableSignature, Error>
pub fn sign_recoverable( &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.
pub fn recover(
&self,
msg: &Message,
sig: &RecoverableSignature
) -> Result<PublicKey, Error>
pub fn recover( &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.
pub fn verify(
&self,
msg: &Message,
sig: &Signature,
pk: &PublicKey
) -> Result<(), Error>
pub fn verify( &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.
