Struct SchnorrSignature 

pub struct SchnorrSignature {
    pub s: Scalar,
    pub r: Point,
}

Schnorr signature containing the signature scalar and commitment point

Fields

s: Scalar

Signature scalar s = k + e*sk

r: Point

Commitment point R = k*G

Implementations

impl SchnorrSignature

pub fn sign(sk: &Scalar, msg: &[u8]) -> Result<Self>

Create a Schnorr signature for a message using a secret key

Arguments

• sk - Secret key scalar
• msg - Message bytes to sign

Returns

A new Schnorr signature

Errors

Returns an error if any cryptographic operation fails

pub fn verify(&self, pk: &Point, msg: &[u8]) -> Result<bool>

Verify a Schnorr signature against a public key and message

Arguments

• pk - Public key point
• msg - Message bytes that were signed

Returns

true if the signature is valid, false otherwise

Errors

Returns an error if any cryptographic operation fails

Trait Implementations

impl Clone for SchnorrSignature

fn clone(&self) -> SchnorrSignature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchnorrSignature

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

Formats the value using the given formatter.

impl Display for SchnorrSignature

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

Formats the value using the given formatter.

impl Hash for SchnorrSignature

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SchnorrSignature

fn eq(&self, other: &SchnorrSignature) -> 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.
