Struct schnorr_fun::adaptor::EncryptedSignature

pub struct EncryptedSignature<S = Public> {
    pub R: Point<EvenY, Public>,
    pub s_hat: Scalar<S, Zero>,
    pub needs_negation: bool,
}

A one-time encrypted Schnorr signature or “adaptor signature”.

Sometimes also called a “pre-signature”.

Fields

R: Point<EvenY, Public>

The R point in the signature

s_hat: Scalar<S, Zero>

The one-time encrypted s value of the signature.

needs_negation: bool

Whether the decryptor should negate their decryption key prior to decryption. This exists as a side effect of using “x-only” public keys.

Implementations

impl<OldSec> EncryptedSignature<OldSec>

#[must_use]pub fn mark<NewSec: Secrecy>(self) -> EncryptedSignature<NewSec>

Marks the encrypted signature with a Secrecy. If it is marked as Secret the operations (e.g. verification) on the signature encryption should be done in constant time.

Trait Implementations

impl<S: Clone> Clone for EncryptedSignature<S>

fn clone(&self) -> EncryptedSignature<S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug> Debug for EncryptedSignature<S>

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

Formats the value using the given formatter.

impl<'de, S> Deserialize<'de> for EncryptedSignature<S> where
    S: Deserialize<'de>, 

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>,

impl<S: PartialEq> PartialEq<EncryptedSignature<S>> for EncryptedSignature<S>

fn eq(&self, other: &EncryptedSignature<S>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &EncryptedSignature<S>) -> bool

This method tests for !=.
