Implementations

impl TransferData

pub fn new(
    transfer_amount: u64,
    spendable_balance: u64,
    spendable_balance_ciphertext: ElGamalCiphertext,
    source_keypair: &ElGamalKeypair,
    dest_pk: ElGamalPubkey,
    auditor_pk: ElGamalPubkey
) -> Self

pub fn decrypt_amount(
    &self,
    role: Role,
    sk: &ElGamalSecretKey
) -> Result<u64, ProofError>

Decrypts transfer amount from transfer data

TODO: This function should run in constant time. Use subtle::Choice for the if statement and make sure that the function does not terminate prematurely due to errors

TODO: Define specific error type for decryption error
