Struct secp256k1::Secp256k1

pub struct Secp256k1<C> { /* fields omitted */ }

The secp256k1 engine, used to execute all signature operations

Methods

impl Secp256k1<None>

pub fn without_caps() -> Secp256k1<None>

Creates a new Secp256k1 context with no capabilities (just de/serialization)

impl Secp256k1<All>

pub fn new() -> Secp256k1<All>

Creates a new Secp256k1 context with all capabilities

impl Secp256k1<SignOnly>

pub fn signing_only() -> Secp256k1<SignOnly>

Creates a new Secp256k1 context that can only be used for signing

impl Secp256k1<VerifyOnly>

pub fn verification_only() -> Secp256k1<VerifyOnly>

Creates a new Secp256k1 context that can only be used for verification

impl<C: Signing> Secp256k1<C>

pub fn sign(&self, msg: &Message, sk: &SecretKey) -> Signature

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 ) -> RecoverableSignature

Constructs a signature for msg using the secret key sk and RFC6979 nonce Requires a signing-capable context.

impl<C: Verification> Secp256k1<C>

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.
