2014-10-17script: move CScriptID to standard.h and add a ctor for creating them from ↵Cory Fields
CScripts This allows for a reversal of the current behavior. This: CScript foo; CScriptID bar(foo.GetID()); Becomes: CScript foo; CScriptID bar(foo); This way, CScript is no longer dependent on CScriptID or Hash();

2014-07-02Use script matching rather than destination matching for watch-only.Pieter Wuille
This changes the keystore data format, wallet format and IsMine logic to detect watch-only outputs based on direct script matching rather than first trying to convert outputs to destinations (addresses). The reason is that we don't know how the software that has the spending keys works. It may support the same types of scripts as us, but that is not guaranteed. Furthermore, it removes the ambiguity between addresses used as identifiers for output scripts or identifiers for public keys. One practical implication is that adding a normal pay-to-pubkey-hash address via importaddress will not cause payments to the corresponding full public key to be detected as IsMine. If that is wanted, add those scripts directly (importaddress now also accepts any hex-encoded script). Conflicts: src/wallet.cpp
2014-07-02Add support for watch-only addressesPieter Wuille
Changes: * Add Add/Have WatchOnly methods to CKeyStore, and implementations in CBasicKeyStore. * Add similar methods to CWallet, and support entries for it in CWalletDB. * Make IsMine in script/wallet return a new enum 'isminetype', rather than a boolean. This allows distinguishing between spendable and unspendable coins. * Add a field fSpendable to COutput (GetAvailableCoins' return type). * Mark watchonly coins in listunspent as 'watchonly': true. * Add 'watchonly' to validateaddress, suppressing script/pubkey/... in this case. Based on a patch by Eric Lombrozo. Conflicts: src/qt/walletmodel.cpp src/rpcserver.cpp src/wallet.cpp

2013-11-10Cleanup code using forward declarations.Brandon Dahler
Use misc methods of avoiding unnecesary header includes. Replace int typedefs with int##_t from stdint.h. Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h. Normalize QT_VERSION ifs where possible. Resolve some indirect dependencies as direct ones. Remove extern declarations from .cpp files.

2013-05-30CSecret/CKey -> CKey/CPubKey split/refactorPieter Wuille
2012-05-24Refactor: split CKeyID/CScriptID/CTxDestination from CBitcoinAddressPieter Wuille
This introduces internal types: * CKeyID: reference (hash160) of a key * CScriptID: reference (hash160) of a script * CTxDestination: a boost::variant of the former two CBitcoinAddress is retrofitted to be a Base58 encoding of a CTxDestination. This allows all internal code to only use the internal types, and only have RPC and GUI depend on the base58 code. Furthermore, the header dependencies are a lot saner now. base58.h is at the top (right below rpc and gui) instead of at the bottom. For the rest: wallet -> script -> keystore -> key. Only keystore still requires a forward declaration of CScript. Solving that would require splitting script into two layers.

2012-05-20Convert UI interface to boost::signals2.Wladimir J. van der Laan
- Signals now go directly from the core to WalletModel/ClientModel. - WalletModel subscribes to signals on CWallet: Prepares for multi-wallet support, by no longer assuming an implicit global wallet. - Gets rid of noui.cpp, the few lines that were left are merged into init.cpp - Rename wxXXX message flags to MF_XXX, to make them UI indifferent. - ThreadSafeMessageBox no longer returns the value `4` which was never used, converted to void.
2012-05-20Fine-grained UI updatesWladimir J. van der Laan
Gets rid of `MainFrameRepaint` in favor of specific update functions that tell the UI exactly what changed. This improves the efficiency of various handlers. Also fixes problems with mined transactions not showing up until restart. The following notifications were added: - `NotifyBlocksChanged`: Block chain changed - `NotifyKeyStoreStatusChanged`: Wallet status (encrypted, locked) changed. - `NotifyAddressBookChanged`: Address book entry changed. - `NotifyTransactionChanged`: Wallet transaction added, removed or updated. - `NotifyNumConnectionsChanged`: Number of connections changed. - `NotifyAlertChanged`: New, updated or cancelled alert. As this finally makes it possible for the UI to know when a new alert arrived, it can be shown as OS notification. These notifications could also be useful for RPC clients. However, currently, they are ignored in bitcoind (in noui.cpp). Also brings back polling with timer for numBlocks in ClientModel. This value updates so frequently during initial download that the number of signals clogs the UI thread and causes heavy CPU usage. And after initial block download, the value changes so rarely that a delay of half a second until the UI updates is unnoticable.

I originally created a pull to replace the "COPYING" in crypter.cpp and crypter.h, but it turned out that COPYING was actually the correct file.

2012-04-17Further reduce header dependenciesPieter Wuille
This commit removes the dependency of serialize.h on PROTOCOL_VERSION, and makes this parameter required instead of implicit. This is much saner, as it makes the places where changing a version number can have an influence obvious.

2012-01-09Compressed pubkeysPieter Wuille
This patch enabled compressed pubkeys when -compressedpubkeys is passed. These are 33 bytes instead of 65, and require only marginally more CPU power when verifying. Compressed pubkeys have a different corresponding address, so it is determined at generation. When -compressedpubkeys is given, all newly generated addresses will use a compressed key, while older/other addresses keep using normal keys. Unpatched clients will relay and verify these transactions.
2011-12-21Revert "Use standard C99 (and Qt) types for 64-bit integers"Wladimir J. van der Laan

2011-12-19Use block times for 'hard' OP_EVAL switchover, and refactored EvalScriptGavin Andresen
so it takes a flag for how to interpret OP_EVAL. Also increased IsStandard size of scriptSigs to 500 bytes, so a 3-of-3 multisig transaction IsStandard.
2011-12-19OP_EVAL implementationGavin Andresen
OP_EVAL is a new opcode that evaluates an item on the stack as a script. It enables a new type of bitcoin address that needs an arbitrarily complex script to redeem.

2011-08-31SetCrypted() obtains keystore lock, to be safe.Gavin Andresen
2011-08-31Fix rpc-hanging deadlocksGavin Andresen
Collapsed multiple wallet mutexes to a single cs_wallet, to avoid deadlocks with wallet methods that acquired locks in different order. Also change master RPC call handler to acquire cs_main and cs_wallet locks before executing RPC calls; requiring each RPC call to acquire the right set of locks in the right order was too error-prone.

2011-07-17Use CBitcoinAddress instead of string/uint160Pieter Wuille
Instead of conversion functions between pubkey/uint160/address in base58.h, have a fully fledged class CBitcoinAddress (CAddress was already taken) to represent addresses.
2011-07-17get rid of mapPubKeysPieter Wuille
Make CKeyStore's interface work on uint160's instead of pubkeys, so no separate global mapPubKeys is necessary anymore.

2011-07-13Add wallet privkey encryption.Matt Corallo
This commit adds support for ckeys, or enCrypted private keys, to the wallet. All keys are stored in memory in their encrypted form and thus the passphrase is required from the user to spend coins, or to create new addresses. Keys are encrypted with AES-256-CBC using OpenSSL's EVP library. The key is calculated via EVP_BytesToKey using SHA512 with (by default) 25000 rounds and a random salt. By default, the user's wallet remains unencrypted until they call the RPC command encryptwallet <passphrase> or, from the GUI menu, Options-> Encrypt Wallet. When the user is attempting to call RPC functions which require the password to unlock the wallet, an error will be returned unless they call walletpassphrase <passphrase> <time to keep key in memory> first. A keypoolrefill command has been added which tops up the users keypool (requiring the passphrase via walletpassphrase first). keypoolsize has been added to the output of getinfo to show the user the number of keys left before they need to specify their passphrase (and call keypoolrefill). Note that walletpassphrase will automatically fill keypool in a separate thread which it spawns when the passphrase is set. This could cause some delays in other threads waiting for locks on the wallet passphrase, including one which could cause the passphrase to be stored longer than expected, however it will not allow the passphrase to be used longer than expected as ThreadCleanWalletPassphrase will attempt to get a lock on the key as soon as the specified lock time has arrived. When the keypool runs out (and wallet is locked) GetOrReuseKeyFromPool returns vchDefaultKey, meaning miners may start to generate many blocks to vchDefaultKey instead of a new key each time. A walletpassphrasechange <oldpassphrase> <newpassphrase> has been added to allow the user to change their password via RPC. Whenever keying material (unencrypted private keys, the user's passphrase, the wallet's AES key) is stored unencrypted in memory, any reasonable attempt is made to mlock/VirtualLock that memory before storing the keying material. This is not true in several (commented) cases where mlock/VirtualLocking the memory is not possible. Although encryption of private keys in memory can be very useful on desktop systems (as some small amount of protection against stupid viruses), on an RPC server, the password is entered fairly insecurely. Thus, the only main advantage encryption has for RPC servers is for RPC servers that do not spend coins, except in rare cases, eg. a webserver of a merchant which only receives payment except for cases of manual intervention. Thanks to jgarzik for the original patch and sipa, gmaxwell and many others for all their input. Conflicts: src/wallet.cpp
