moneromooo-monero	1e21651f24	rct: use the already defined H where possible ... Found by luigi1111w	2016-08-28 21:29:29 +01:00
moneromooo-monero	07d353dfc6	wallet: handle 0 change properly ... With RCT, we allow 0 size outputs, to try and encourage txes with two inputs and two outputs. Consolidation would then have two non zero inputs, one zero output, and one larger output.	2016-08-28 21:29:27 +01:00
moneromooo-monero	e81a2b2cfa	port get_tx_key/check_tx_key to rct	2016-08-28 21:29:24 +01:00
moneromooo-monero	e06faefde4	tests: add basic tests for simple rct api	2016-08-28 21:29:22 +01:00
moneromooo-monero	a4d4d6194b	integrate simple rct api	2016-08-28 21:29:20 +01:00
moneromooo-monero	1e8d37e7d8	serialization: add override for serializing bool	2016-08-28 21:29:19 +01:00
Shen Noether	dbb5f2d6a3	ringct: optimization/cleanup of hash functions	2016-08-28 21:29:16 +01:00
Shen Noether	4fd01f2bee	ringct: "simple" ringct variant ... Allows the fake outs to be in different positions for each ring. For rct inputs only.	2016-08-28 21:29:14 +01:00
moneromooo-monero	37c895e5e3	wallet: rct specific output selection ... Before the normal selection, we attempt to find either one or two suitable outputs to use as inputs to the rct tx. The intent is that most rct txes will have one or two inputs, and we want all to look the same if possible. When two outputs are needed, we try to find a pair which are not related (ie, by being from the same or similar block height).	2016-08-28 21:29:11 +01:00
moneromooo-monero	1181c57967	wallet: make sweep_all work with rct txes too	2016-08-28 21:29:09 +01:00
moneromooo-monero	c2ec6d35b9	mixable transactions must be rct for v3	2016-08-28 21:29:07 +01:00
moneromooo-monero	1017a75460	wallet: factor transfer_rct code with transfer code ... The "transfer" simplewallet command is renamed to "transfer_original". "transfer_new" is renamed "transfer", "transfer_rct" is removed, and the new "transfer" now selects rct or non rct transactions based on the current block height.	2016-08-28 21:29:05 +01:00
moneromooo-monero	f5465d8246	Condition v2 txes on v3 hard fork	2016-08-28 21:29:04 +01:00
moneromooo-monero	59a66e209a	move the rct commitments to the output_amounts database ... Since these are needed at the same time as the output pubkeys, this is a whole lot faster, and takes less space. Only outputs of 0 amount store the commitment. When reading other outputs, a fake commitment is regenerated on the fly. This avoids having to rewrite the database to add space for fake commitments for existing outputs. This code relies on two things: - LMDB must support fixed size records per key, rather than per database (ie, all records on key 0 are the same size, all records for non 0 keys are same size, but records from key 0 and non 0 keys do have different sizes). - the commitment must be directly after the rest of the data in outkey and output_data_t.	2016-08-28 21:29:02 +01:00
moneromooo-monero	6d0e47148b	rct: add the tx prefix hash into the MLSAG ... to protect the non-signatures parts of the tx from tampering.	2016-08-28 21:28:58 +01:00
moneromooo-monero	35dce5c70c	ringct: fix size unit mismatch calling keccak	2016-08-28 21:28:57 +01:00
moneromooo-monero	20e50ec7f7	ringct: do not serialize what can be reconstructed ... The mixRing (output keys and commitments) and II fields (key images) can be reconstructed from vin data. This saves some modest amount of space in the tx.	2016-08-28 21:28:55 +01:00
moneromooo-monero	106e3dc3d4	Add rct core tests	2016-08-28 21:28:53 +01:00
moneromooo-monero	ada527558f	Use the supplied hard fork version in validate_miner_transaction ... rather than using the current one. No functional changes, but may save some bugs in the future.	2016-08-28 21:28:51 +01:00
moneromooo-monero	acbe06d8e9	wallet: update spent status when an accepted tx disappears	2016-08-28 21:28:49 +01:00
moneromooo-monero	089df4af83	wallet: reset output spent status on blockchain reorg ... If the blockchain gets reorganized, all outputs spent in the part of the blockchain that's blown away need to be reset to unspent (they may end up spent again on the blocks that replace the blocks that are removed, however).	2016-08-28 21:28:47 +01:00
moneromooo-monero	73d59f17e1	ringct: catch errors from ge_frombytes_vartime	2016-08-28 21:28:45 +01:00
moneromooo-monero	161551e13b	tests: test for ringct rctSig data sizes ... ie, more data or less data than expected in various fields	2016-08-28 21:28:42 +01:00

moneromooo-monero	229968eafc	ringct: change asserts to return false for boolean functions	2016-08-28 21:28:39 +01:00
moneromooo-monero	dc4aad7eb5	add rct to the protocol ... It is not yet constrained to a fork, so don't use on the real network or you'll be orphaned or rejected.	2016-08-28 21:28:37 +01:00
moneromooo-monero	211d1db762	db_lmdb: update reset for recent db changes ... - we need to drop the new m_tx_indices database - we reset the version to current version This fixes the core tests failing to initialize.	2016-08-28 21:28:35 +01:00
moneromooo-monero	dee42d6dac	ringct: add functions to commit to an amount ... One to commit to an amount with zero key (for use with fake commitments for pre-rct outputs), and one with an arbitrary key (for rct outputs).	2016-08-28 21:28:33 +01:00
moneromooo-monero	cc7f449d57	make rct tx serialization work ... It may be suboptimal, but it's a pain to have to rebuild everything when some of this changes. Also, no clue why there seems to be two different code paths for serializing a tx...	2016-08-28 21:28:31 +01:00
moneromooo-monero	e70e8a69f4	crypto: error out where appropriate	2016-08-28 21:28:29 +01:00

moneromooo-monero	e99904ac31	ringct: make fee optional	2016-08-28 21:28:25 +01:00
Shen Noether	f8c04ad94f	ringct: txn fee stuff	2016-08-28 21:28:23 +01:00
moneromooo-monero	66f96260b2	ringct: new {gen,decode}Rct APIs for convenience ... A new version of genRct takes the mixRing as parameter, instead of the inPk. inPk are part of the mixRing, and it is cleaner to pass the mixRing data than to fetch it from the RingCT code. A new version of decodeRct also returns the mask. Also, failure to decode throws, so errors are properly detected.	2016-08-28 21:28:21 +01:00
