This library implements the BIP47 standard and provides functionality for generating static payment codes that two parties can use to create a private payment address space between them.
Original specification: BIP-0047.
// Alice constructs her own payment code using a BIP32 seed
let alice_private = PrivateCode::from_seed(&alice_seed, 0, Network::Bitcoin).unwrap();
// Alice parses Bob's payment code
let bob_public = PublicCode::from_wif("PM8TJS2JxQ5ztXUpBBRnpTbcUXbUHy2T1abfrb3KkAAtMEGNbey4oumH7Hc578WgQJhPjBxteQ5GHHToTYHE3A1w6p7tU6KSoFmWBVbFGjKPisZDbP97").unwrap();
// Alice calculates Bob's receive address at index 0, known only to them
let bob_address_0 = bob_public.address(&alice_private, 0, false).unwrap();
// Alice can now pay Bob privately
assert_eq!("12edoJAofkjCsWrtmVjuQgMUKJ6Z7Ntpzx", bob_address_0.to_string());The minimum supported Rust version is 1.29.
