Struct Signature

pub struct Signature(/* private fields */);

Represents an ECDSA signature based on the secp256k1 curve with a recoverable public key. This signature encodes the 2-bit recovery information into the uppermost bits of MSB of the S value, which are never used by this ECDSA instantiation over secp256k1. The instance holds the byte array consisting of R and S values with the recovery bit already embedded in S.

Implementations

impl Signature

pub fn new(raw_bytes: &[u8], recovery: u8) -> Signature

pub fn sign_message(message: &[u8], chain_keypair: &ChainKeypair) -> Signature

Signs the given message using the chain private key.

pub fn sign_hash(hash: &[u8], chain_keypair: &ChainKeypair) -> Signature

Signs the given hash using the raw private key.

pub fn verify_message(&self, message: &[u8], public_key: &PublicKey) -> bool

Verifies this signature against the given message and a public key object

pub fn verify_hash(&self, hash: &[u8], public_key: &PublicKey) -> bool

Verifies this signature against the given hash and a public key object

pub fn raw_signature(&self) -> ([u8; 64], u8)

Returns the raw signature, without the encoded public key recovery bit and the recovery bit as a separate value.

Trait Implementations

impl AsRef<[u8]> for Signature

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl BytesRepresentable for Signature

const SIZE: usize = 64usize

Size of the encoded byte array.

fn into_boxed(self) -> Box<[u8]>

Convenience function to copy this type’s binary representation into a Box.

impl Clone for Signature

fn clone(&self) -> Signature

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Signature

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Signature

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Signature

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Signature

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&[u8]> for Signature

type Error = GeneralError

The type returned in the event of a conversion error.

fn try_from(value: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Signature

impl Eq for Signature
