Message structure with value commitment

Implementations

[src]

impl Message

[src]

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

[src]

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

[src]

pub fn hash(&self) -> BlsScalar

Sponge hash of the message hash inputs representation

[src]

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

Value commitment representation of the message

[src]

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

Nonce used for the encryption of the value and blinding factor

[src]

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

Returns the cipher of the encrypted data

[src]

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
