ciphertext_hi: TransferAmountEncryption

Group encryption of the high 32 bits of the transfer amount

transfer_with_fee_pubkeys: TransferWithFeePubkeys

The public encryption keys associated with the transfer: source, dest, and auditor

ciphertext_new_source: ElGamalCiphertext

The final spendable ciphertext after the transfer,

ciphertext_fee: FeeEncryption

fee_parameters: FeeParameters

proof: TransferWithFeeProof

Implementations

impl TransferWithFeeData

pub fn new(
    transfer_amount: u64,
    (u64, &ElGamalCiphertext),
    keypair_source: &ElGamalKeypair,
    (&ElGamalPubkey, &ElGamalPubkey),
    fee_parameters: FeeParameters,
    pubkey_withdraw_withheld_authority: &ElGamalPubkey
) -> Result<TransferWithFeeData, ProofError>

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

Decrypts transfer amount from transfer-with-fee 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
