2011-12-27Fix OP_EVAL recursion depth countingWladimir J. van der Laan
2011-12-22Fix broken ExtractAddress (refactored, made callers check for addresses in ↵Gavin Andresen
keystore if they care)
2011-12-19Update bitcoin address numbers for latest luke-jr/sipa schemeGavin Andresen
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.
2011-12-19Interpret OP_EVAL as OP_NOP until Feb 1, 2012Gavin Andresen
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.
2011-12-19Support 3 new multisignature IsStandard transactionsGavin Andresen
Initial support for (a and b), (a or b), and 2-of-3 escrow transactions (where a, b, and c are keys).

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.

2011-07-26Bugfix: don't overuse limited ExtractAddressPieter Wuille
ExtractAddress was called with the keystore as argument in RPC and UI, limiting results to own keys. This caused empty "address" fields.

2011-07-17split off CBase58Data from CBitcoinAddressPieter Wuille
Split off features unrelated to addresses from CBitcoinAddress to CBase58Data, so they can be reused.
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.
2011-07-13fix warning: X enumeration values not handled in switch [-Wswitch-enum]Giel van Schijndel

2011-07-13Do not use obsolete CPrivKey for passing keys aroundPieter Wuille
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

2011-06-20Bugfixes walletclassPieter Wuille
Some problems found by ius: * compiler complains with no return after critical section block * CKeyStore::GetPrivKey(key) was undefined for unknown key * missing return statement in GetChange()
2011-06-15CWallet classPieter Wuille
* A new class CKeyStore manages private keys, and script.cpp depends on access to CKeyStore. * A new class CWallet extends CKeyStore, and contains all former wallet-specific globals; CWallet depends on script.cpp, not the other way around. * Wallet-specific functions in CTransaction/CTxIn/CTxOut (GetDebit, GetCredit, GetChange, IsMine, IsFromMe), are moved to CWallet, taking their former 'this' argument as an explicit parameter * CWalletTx objects know which CWallet they belong to, for convenience, so they have their own direct (and caching) GetDebit/... functions. * Some code was moved from CWalletDB to CWallet, such as handling of reserve keys. * Main.cpp keeps a set of all 'registered' wallets, which should be informed about updates to the block chain, and does not have any notion about any 'main' wallet. Function in main.cpp that require a wallet (such as GenerateCoins), take an explicit CWallet* argument. * The actual CWallet instance used by the application is defined in init.cpp as "CWallet* pwalletMain". rpc.cpp and ui.cpp use this variable. * Functions in main.cpp and db.cpp that are not used by other modules are marked static. * The code for handling the 'submitorder' message is removed, as it not really compatible with the idea that a node is independent from the wallet(s) connected to it, and obsolete anyway.
