From 998777ecd71fee25636f6ef40f05f88251d03e96 Mon Sep 17 00:00:00 2001 From: stoffu Date: Tue, 12 Sep 2017 10:05:41 +0900 Subject: [PATCH] Tx proof (revised): - refactoring: proof generation/checking code was moved from simplewallet.cpp to wallet2.cpp - allow an arbitrary message to be signed together with txid - introduce two types (outbound & inbound) of tx proofs; with the same syntax, inbound is selected when
belongs to this wallet, outbound otherwise. see GitHub thread for more discussion - wallet RPC: added get_tx_key, check_tx_key, get_tx_proof, check_tx_proof - wallet API: moved WalletManagerImpl::checkPayment to Wallet::checkTxKey, added Wallet::getTxProof/checkTxProof - get_tx_key/check_tx_key: handle additional tx keys by concatenating them into a single string --- src/simplewallet/simplewallet.cpp | 466 +++++-------------- src/simplewallet/simplewallet.h | 1 - src/wallet/api/wallet.cpp | 140 +++++- src/wallet/api/wallet.h | 3 + src/wallet/api/wallet_manager.cpp | 149 ------ src/wallet/api/wallet_manager.h | 1 - src/wallet/wallet2.cpp | 349 ++++++++++++++ src/wallet/wallet2.h | 4 + src/wallet/wallet2_api.h | 16 +- src/wallet/wallet_rpc_server.cpp | 161 +++++++ src/wallet/wallet_rpc_server.h | 8 + src/wallet/wallet_rpc_server_commands_defs.h | 108 +++++ src/wallet/wallet_rpc_server_error_codes.h | 2 + 13 files changed, 876 insertions(+), 532 deletions(-) diff --git a/src/simplewallet/simplewallet.cpp b/src/simplewallet/simplewallet.cpp index 37db00bc1..d971f4fed 100644 --- a/src/simplewallet/simplewallet.cpp +++ b/src/simplewallet/simplewallet.cpp @@ -929,7 +929,7 @@ simple_wallet::simple_wallet() m_cmd_binder.set_handler("rescan_spent", boost::bind(&simple_wallet::rescan_spent, this, _1), tr("Rescan blockchain for spent outputs")); m_cmd_binder.set_handler("get_tx_key", boost::bind(&simple_wallet::get_tx_key, this, _1), tr("Get transaction key (r) for a given ")); m_cmd_binder.set_handler("check_tx_key", boost::bind(&simple_wallet::check_tx_key, this, _1), tr("Check amount going to
