Struct keys::SECP256K1

pub struct SECP256K1 { /* fields omitted */ }

Methods from __Deref<Target = Secp256k1>

pub fn sign_schnorr(     &self,     msg: &Message,     sk: &SecretKey ) -> Result<Signature, Error>

Create a Schnorr signature

pub fn verify_schnorr(     &self,     msg: &Message,     sig: &Signature,     pk: &PublicKey ) -> Result<(), Error>

Verify a Schnorr signature

pub fn recover_schnorr(     &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.

pub fn generate_keypair<R>(     &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.

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>

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>

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>

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.
