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();

2014-08-26Split up util.cpp/hWladimir J. van der Laan
Split up util.cpp/h into: - string utilities (hex, base32, base64): no internal dependencies, no dependency on boost (apart from foreach) - money utilities (parsesmoney, formatmoney) - time utilities (gettime*, sleep, format date): - and the rest (logging, argument parsing, config file parsing) The latter is basically the environment and OS handling, and is stripped of all utility functions, so we may want to rename it to something else than util.cpp/h for clarity (Matt suggested osinterface). Breaks dependency of sha256.cpp on all the things pulled in by util.
2014-08-10Dont run full check every time we decrypt wallet.Matt Corallo
2014-08-10Make CCryptoKeyStore::Unlock check all keys.Gregory Maxwell
CCryptoKeyStore::Unlock has a loop to attempt decrypting each key which only executes once, likely due to a simple mistake when the code was originally written. This patch fixes the behavior by making it check all keys. It also adds a fatal assertion in the case some decrypt but some do not, since that indicates that the wallet is in some kind of really bad state. This may make unlocking noticeably slower on wallets with many keys.

This breaks the dependency on crypter for disable-wallet builds.
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.

2012-11-09don't use memset() in privacy/security relevant code partsPhilip Kaufmann
As memset() can be optimized out by a compiler it should not be used in privacy/security relevant code parts. OpenSSL provides the safe OPENSSL_cleanse() function in crypto.h, which perfectly does the job of clean and overwrite data. For details see: http://www.viva64.com/en/b/0178/ - change memset() to OPENSSL_cleanse() where appropriate - change a hard-coded number from netbase.cpp into a sizeof()
2012-08-23Make CCrypter use LockedPageManager to manage locked pagesWladimir J. van der Laan
Replace direct calls to mlock. Also, change the class to lock the memory areas in the constructor and unlock them again in the destructor. This makes sure that locked pages won't leak.

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.

2011-11-26Implement an mlock()'d string class for storing passphrasesDylan Noblesmith
SecureString is identical to std::string except with secure_allocator substituting for std::allocator. This makes casting between them impossible, so converting between the two at API boundaries requires calling ::c_str() for now.
2011-10-07Fix build on windows and macGavin Andresen
Replaced all occurrences of #if* __WXMSW__ with WIN32, and all occurrences of __WXMAC_OSX__ with MAC_OSX, and made sure those are defined appropriately in the makefile and bitcoin-qt.pro.
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
