2019-03-05epee: add SSL supportMartijn Otto1-1/+2
RPC connections now have optional tranparent SSL. An optional private key and certificate file can be passed, using the --{rpc,daemon}-ssl-private-key and --{rpc,daemon}-ssl-certificate options. Those have as argument a path to a PEM format private private key and certificate, respectively. If not given, a temporary self signed certificate will be used. SSL can be enabled or disabled using --{rpc}-ssl, which accepts autodetect (default), disabled or enabled. Access can be restricted to particular certificates using the --rpc-ssl-allowed-certificates, which takes a list of paths to PEM encoded certificates. This can allow a wallet to connect to only the daemon they think they're connected to, by forcing SSL and listing the paths to the known good certificates. To generate long term certificates: openssl genrsa -out /tmp/KEY 4096 openssl req -new -key /tmp/KEY -out /tmp/REQ openssl x509 -req -days 999999 -sha256 -in /tmp/REQ -signkey /tmp/KEY -out /tmp/CERT /tmp/KEY is the private key, and /tmp/CERT is the certificate, both in PEM format. /tmp/REQ can be removed. Adjust the last command to set expiration date, etc, as needed. It doesn't make a whole lot of sense for monero anyway, since most servers will run with one time temporary self signed certificates anyway. SSL support is transparent, so all communication is done on the existing ports, with SSL autodetection. This means you can start using an SSL daemon now, but you should not enforce SSL yet or nothing will talk to you.

2018-12-04device/trezor: ask for KI sync on first refreshDusan Klinec1-1/+6
When doing a first refresh on HW-token based wallet KI sync is required if money were received. Received money may indicate wallet was already used before the restore I.e., some transaction could have been already sent from the wallet. The spent UTXO would not be detected as spent which could lead to double spending errors on submitting a new transaction. Thus if the wallet is HW-token based with the cold signing protocol and the first refresh detected received money the user is asked to perform the key image sync.
2018-12-04device: enable to use multiple independent device walletsDusan Klinec1-0/+4
- adds a new option `--hw-device-deriv-path` to the simple wallet. Enables to specify wallet derivation path / wallet code (path avoided so it can be misinterpreted as a file path). - devices can use different derivation mechanisms. Trezor uses standard SLIP-10 mechanism with fixed SLIP-44 prefix for Monero - Trezor: when empty, the default derivation mechanism is used with 44'/128'/0'. When entered the derivation path is 44'/128'/PATH. - Trezor: the path is always taken as elements are hardened (1<<31 bit turned on)
2018-11-29device/trezor: passphrase entry on hostDusan Klinec1-0/+22
- simple device callback object added. Device can request passphrase/PIN entry via the callback or notify user some action is required - callback is routed to wallet2, which routes the callback to i_wallet_callback so CLI or GUI wallets can support passphrase entry for HW tokens - wallet: device open needs wallet callback first - passphrase protected device needs wallet callback so user can enter passphrase

This is based on how much an attacking miner stands to lose in block rewardy by mining a private chain which double spends a payment. This is not foolproof, since mining is based on luck, and breaks down as the attacking miner nears 50% of the network hash rate, and the estimation is based on a constant block reward.

2018-03-16wallet: key reuse mitigation optionsmoneromooo-monero1-0/+6
If a pre-fork output is spent on both Monero and attack chain, any post-fork output can be deduced to be a fake output, thereby decreasing the effective ring size. The segregate-per-fork-outputs option, on by default, allows selecting only pre-fork outputs in this case, so that the same ring can be used when spending it on the other side, which does not decrease the effective ring size. This is intended to be SET when intending to spend Monero on the attack fork, and to be UNSET if not intending to spend Monero on the attack fork (since it leaks the fact that the output being spent is pre-fork). If the user is not certain yet whether they will spend pre-fork outputs on a key reusing fork, the key-reuse-mitigation2 option should be SET instead. If you use this option and intend to spend Monero on both forks, then spend real Monero first.
2018-03-16wallet: add shared ring databasemoneromooo-monero1-1/+16
This maps key images to rings, so that different forks can reuse the rings by key image. This avoids revealing the real inputs like would happen if two forks spent the same outputs with different rings. This database is meant to be shared with all Monero forks which don't bother making a new chain, putting users' privacy at risk in the process. It is placed in a shared data directory by default ($HOME/.shared-ringdb on UNIX like systems). You may use --shared-ringdb-dir to override this location, and should then do so for all Monero forks for them to share the database.

2018-03-04Code modifications to integrate Ledger HW device into monero-wallet-cli.cslashm1-1/+11
The basic approach it to delegate all sensitive data (master key, secret ephemeral key, key derivation, ....) and related operations to the device. As device has low memory, it does not keep itself the values (except for view/spend keys) but once computed there are encrypted (with AES are equivalent) and return back to monero-wallet-cli. When they need to be manipulated by the device, they are decrypted on receive. Moreover, using the client for storing the value in encrypted form limits the modification in the client code. Those values are transfered from one C-structure to another one as previously. The code modification has been done with the wishes to be open to any other hardware wallet. To achieve that a C++ class hw::Device has been introduced. Two initial implementations are provided: the "default", which remaps all calls to initial Monero code, and the "Ledger", which delegates all calls to Ledger device.

Scheme by luigi1111: Multisig for RingCT on Monero 2 of 2 User A (coordinator): Spendkey b,B Viewkey a,A (shared) User B: Spendkey c,C Viewkey a,A (shared) Public Address: C+B, A Both have their own watch only wallet via C+B, a A will coordinate spending process (though B could easily as well, coordinator is more needed for more participants) A and B watch for incoming outputs B creates "half" key images for discovered output D: I2_D = (Hs(aR)+c) * Hp(D) B also creates 1.5 random keypairs (one scalar and 2 pubkeys; one on base G and one on base Hp(D)) for each output, storing the scalar(k) (linked to D), and sending the pubkeys with I2_D. A also creates "half" key images: I1_D = (Hs(aR)+b) * Hp(D) Then I_D = I1_D + I2_D Having I_D allows A to check spent status of course, but more importantly allows A to actually build a transaction prefix (and thus transaction). A builds the transaction until most of the way through MLSAG_Gen, adding the 2 pubkeys (per input) provided with I2_D to his own generated ones where they are needed (secret row L, R). At this point, A has a mostly completed transaction (but with an invalid/incomplete signature). A sends over the tx and includes r, which allows B (with the recipient's address) to verify the destination and amount (by reconstructing the stealth address and decoding ecdhInfo). B then finishes the signature by computing ss[secret_index][0] = ss[secret_index][0] + k - cc[secret_index]*c (secret indices need to be passed as well). B can then broadcast the tx, or send it back to A for broadcasting. Once B has completed the signing (and verified the tx to be valid), he can add the full I_D to his cache, allowing him to verify spent status as well. NOTE: A and B *must* present key A and B to each other with a valid signature proving they know a and b respectively. Otherwise, trickery like the following becomes possible: A creates viewkey a,A, spendkey b,B, and sends a,A,B to B. B creates a fake key C = zG - B. B sends C back to A. The combined spendkey C+B then equals zG, allowing B to spend funds at any time! The signature fixes this, because B does not know a c corresponding to C (and thus can't produce a signature). 2 of 3 User A (coordinator) Shared viewkey a,A "spendkey" j,J User B "spendkey" k,K User C "spendkey" m,M A collects K and M from B and C B collects J and M from A and C C collects J and K from A and B A computes N = nG, n = Hs(jK) A computes O = oG, o = Hs(jM) B anc C compute P = pG, p = Hs(kM) || Hs(mK) B and C can also compute N and O respectively if they wish to be able to coordinate Address: N+O+P, A The rest follows as above. The coordinator possesses 2 of 3 needed keys; he can get the other needed part of the signature/key images from either of the other two. Alternatively, if secure communication exists between parties: A gives j to B B gives k to C C gives m to A Address: J+K+M, A 3 of 3 Identical to 2 of 2, except the coordinator must collect the key images from both of the others. The transaction must also be passed an additional hop: A -> B -> C (or A -> C -> B), who can then broadcast it or send it back to A. N-1 of N Generally the same as 2 of 3, except participants need to be arranged in a ring to pass their keys around (using either the secure or insecure method). For example (ignoring viewkey so letters line up): [4 of 5] User: spendkey A: a B: b C: c D: d E: e a -> B, b -> C, c -> D, d -> E, e -> A Order of signing does not matter, it just must reach n-1 users. A "remaining keys" list must be passed around with the transaction so the signers know if they should use 1 or both keys. Collecting key image parts becomes a little messy, but basically every wallet sends over both of their parts with a tag for each. Thia way the coordinating wallet can keep track of which images have been added and which wallet they come from. Reasoning: 1. The key images must be added only once (coordinator will get key images for key a from both A and B, he must add only one to get the proper key actual key image) 2. The coordinator must keep track of which helper pubkeys came from which wallet (discussed in 2 of 2 section). The coordinator must choose only one set to use, then include his choice in the "remaining keys" list so the other wallets know which of their keys to use. You can generalize it further to N-2 of N or even M of N, but I'm not sure there's legitimate demand to justify the complexity. It might also be straightforward enough to support with minimal changes from N-1 format. You basically just give each user additional keys for each additional "-1" you desire. N-2 would be 3 keys per user, N-3 4 keys, etc. The process is somewhat cumbersome: To create a N/N multisig wallet: - each participant creates a normal wallet - each participant runs "prepare_multisig", and sends the resulting string to every other participant - each participant runs "make_multisig N A B C D...", with N being the threshold and A B C D... being the strings received from other participants (the threshold must currently equal N) As txes are received, participants' wallets will need to synchronize so that those new outputs may be spent: - each participant runs "export_multisig FILENAME", and sends the FILENAME file to every other participant - each participant runs "import_multisig A B C D...", with A B C D... being the filenames received from other participants Then, a transaction may be initiated: - one of the participants runs "transfer ADDRESS AMOUNT" - this partly signed transaction will be written to the "multisig_monero_tx" file - the initiator sends this file to another participant - that other participant runs "sign_multisig multisig_monero_tx" - the resulting transaction is written to the "multisig_monero_tx" file again - if the threshold was not reached, the file must be sent to another participant, until enough have signed - the last participant to sign runs "submit_multisig multisig_monero_tx" to relay the transaction to the Monero network

2017-11-06track double spending in the txpoolmoneromooo-monero1-7/+32
Transactions in the txpool are marked when another transaction is seen double spending one or more of its inputs. This is then exposed wherever appropriate. Note that being marked with this "double spend seen" flag does NOT mean this transaction IS a double spend and will never be mined: it just means that the network has seen at least another transaction spending at least one of the same inputs, so care should be taken to wait for a few confirmations before acting upon that transaction (ie, mostly of use for merchants wanting to accept unconfirmed transactions).

2017-03-25wallet: option to merge destinationsmoneromooo-monero1-2/+5
With the change from the original transfer method to the new algorithm, payments to the same destination were merged. It seemed like a good idea, optimizing space. However, it is a useful tool for people who want to split large outputs into several smaller ones (ie, service providers making frequent payments, and who do not like a large chunk of their balance being locked for 10 blocks after each payment). Default to off, which is a change from the previous behavior.
2017-03-24wallet: try to save large outputs when using an unneeded second inputmoneromooo-monero1-2/+9
When a single input is enough to satisfy a transfer, the code would previously try to add a second input, to match the "canonical" makeup of a transaction with two inputs and two outputs. This would cause wallets to slowly merge outputs till all the monero ends up in a single output, which causes trouble when making two transactions one after the other, since change is locked for 10 blocks, and an increasing portion of the remaining balance would end up locked on each transaction. There are two new settings (min-output-count and min-output-value) which can control when to stop adding such unneeded second outputs. The idea is that small "dust" outputs will still get added, but larger ones will not. Enable with, eg: set min-output-count 10 set min-output-value 30 to avoid using an unneeded second output of 30 monero or more, if there would be less than 10 such outputs left. This does not invalidate any other reason why such outputs would be used (ie, when they're really needed to satisfy a transfer, or when randomly picked in the normal course of selection). This may be improved in the future.

2017-03-20wallet2: speed up transactions using remote nodesmoneromooo-monero1-0/+2
Asking for a full histogram from a remote node (since it's untrusted) is pretty slow, and spams the remote node, so we replace it by only adding a second input if we have rct ones, which are for all intents and purposes always mixable.

Minimum mixin 4 and enforced ringct is moved from v5 to v6. v5 is now used for an increased minimum block size (from 60000 to 300000) to cater for larger typical/minimum transaction size. The fee algorithm is also changed to decrease the base per kB fee, and add a cheap tier for those transactions which we do not care if they get delayed (or even included in a block).

2017-01-16Change logging to easylogging++moneromooo-monero1-0/+4
This replaces the epee and data_loggers logging systems with a single one, and also adds filename:line and explicit severity levels. Categories may be defined, and logging severity set by category (or set of categories). epee style 0-4 log level maps to a sensible severity configuration. Log files now also rotate when reaching 100 MB. To select which logs to output, use the MONERO_LOGS environment variable, with a comma separated list of categories (globs are supported), with their requested severity level after a colon. If a log matches more than one such setting, the last one in the configuration string applies. A few examples: This one is (mostly) silent, only outputting fatal errors: MONERO_LOGS=*:FATAL This one is very verbose: MONERO_LOGS=*:TRACE This one is totally silent (logwise): MONERO_LOGS="" This one outputs all errors and warnings, except for the "verify" category, which prints just fatal errors (the verify category is used for logs about incoming transactions and blocks, and it is expected that some/many will fail to verify, hence we don't want the spam): MONERO_LOGS=*:WARNING,verify:FATAL Log levels are, in decreasing order of priority: FATAL, ERROR, WARNING, INFO, DEBUG, TRACE Subcategories may be added using prefixes and globs. This example will output net.p2p logs at the TRACE level, but all other net* logs only at INFO: MONERO_LOGS=*:ERROR,net*:INFO,net.p2p:TRACE Logs which are intended for the user (which Monero was using a lot through epee, but really isn't a nice way to go things) should use the "global" category. There are a few helper macros for using this category, eg: MGINFO("this shows up by default") or MGINFO_RED("this is red"), to try to keep a similar look and feel for now. Existing epee log macros still exist, and map to the new log levels, but since they're used as a "user facing" UI element as much as a logging system, they often don't map well to log severities (ie, a log level 0 log may be an error, or may be something we want the user to see, such as an important info). In those cases, I tried to use the new macros. In other cases, I left the existing macros in. When modifying logs, it is probably best to switch to the new macros with explicit levels. The --log-level options and set_log commands now also accept category settings, in addition to the epee style log levels.
2017-01-14wallet2: use at least two rct inputs if possiblemoneromooo-monero1-2/+2
If we'd make a rct tx with just one input, we try to add a second one to match the 2/2 ideal. This means more txes use that template (and are thus using a larger anonymity set), and it coalesces outputs "for free". We use the smallest amount outputs in priority for this, so we can "clean" the wallet at the same time.
