Struct phoenix_core::message::Message

pub struct Message { /* fields omitted */ }

Message structure with value commitment

Implementations

impl Message

pub fn new<R: RngCore + CryptoRng>(
    rng: &mut R,
    r: &JubJubScalar,
    psk: &PublicSpendKey,
    value: u64
) -> Self

Create a new message

r will be later used to decrypt the value and blinding factor

pub fn to_hash_inputs(&self) -> [BlsScalar; 6]

Represent the message as a sequence of scalars to be used as input for sponge hash functions

It is composed by 3 scalars, in order:

• Value commitment X
• Value commitment Y
• Nonce

And also appends the scalars that composes the PoseidonCipher

pub fn hash(&self) -> BlsScalar

Sponge hash of the message hash inputs representation

pub const fn value_commitment(&self) -> &JubJubExtended

Value commitment representation of the message

pub const fn nonce(&self) -> &JubJubScalar

Nonce used for the encryption of the value and blinding factor

pub const fn cipher(&self) -> &[BlsScalar; 3]

Returns the cipher of the encrypted data

pub fn decrypt(
    &self,
    r: &JubJubScalar,
    psk: &PublicSpendKey
) -> Result<(u64, JubJubScalar), Error>

Decrypt the value and blinding factor provided the r used in the creation of the message

Trait Implementations

impl Clone for Message

fn clone(&self) -> Message

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Message

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

Formats the value using the given formatter.

impl Default for Message

fn default() -> Message

Returns the “default value” for a type.

impl PartialEq<Message> for Message

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

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

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

This method tests for !=.

impl Serializable<{ JubJubAffine::SIZE + JubJubScalar::SIZE + PoseidonCipher::SIZE }> for Message

type Error = Error

The type returned in the event of a conversion error.

fn to_bytes(&self) -> [u8; 160]

Serialize Self into a [[u8; N]].

fn from_bytes(bytes: &[u8; 160]) -> Result<Self, Self::Error>

Deserialize a [&[u8; N]] into Self, it might be fail.

const SIZE: usize

The size of
