Fields

ciphertext_lo: TransferAmountEncryption

Group encryption of the low 32 bits of the transfer amount

ciphertext_hi: TransferAmountEncryption

Group encryption of the high 32 bits of the transfer amount

transfer_pubkeys: TransferPubkeys

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

ciphertext_new_source: ElGamalCiphertext

The final spendable ciphertext after the transfer

proof: TransferProof

Zero-knowledge proofs for Transfer

Implementations

impl TransferData

pub fn new(
    transfer_amount: u64,
    (u64, &ElGamalCiphertext),
    keypair_source: &ElGamalKeypair,
    (&ElGamalPubkey, &ElGamalPubkey)
) -> Result<TransferData, ProofError>

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
