Struct BlindSignature 

pub struct BlindSignature {
    pub amount: Amount,
    pub keyset_id: Id,
    pub c: PublicKey,
    pub dleq: Option<BlindSignatureDleq>,
}

Blind Signature (also called promise)

Fields

amount: Amount

Amount

The value of the blinded token.

keyset_id: Id

Keyset ID

ID of the mint keys that signed the token.

c: PublicKey

Blinded signature (C_)

The blinded signature on the secret message B_ of BlindedMessage.

dleq: Option<BlindSignatureDleq>

Implementations

impl BlindSignature

pub fn new( amount: Amount, blinded_signature: PublicKey, keyset_id: Id, blinded_message: &PublicKey, mint_secretkey: SecretKey, ) -> Result<BlindSignature, Error>

New DLEQ

pub fn verify_dleq( &self, mint_pubkey: PublicKey, blinded_message: PublicKey, ) -> Result<(), Error>

Verify dleq on proof

pub fn add_dleq_proof( &mut self, blinded_message: &PublicKey, mint_secretkey: &SecretKey, ) -> Result<(), Error>

Add Dleq to proof

Trait Implementations

impl Clone for BlindSignature

fn clone(&self) -> BlindSignature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlindSignature

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BlindSignature

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for BlindSignature

fn cmp(&self, other: &BlindSignature) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for BlindSignature

fn eq(&self, other: &BlindSignature) -> 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 PartialOrd for BlindSignature

fn partial_cmp(&self, other: &BlindSignature) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for BlindSignature

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
