| * Split up util.cpp/hWladimir J. van der Laan2014-08-261-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Use script matching rather than destination matching for watch-only.Pieter Wuille2014-07-021-15/+7
| | | | | | | | | | | | | | | | | | | 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
* Add support for watch-only addressesPieter Wuille2014-07-021-13/+39
| | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | a81cd968 introduced a malleability breaker for signatures (using an even value for S). In e0e14e43 this was changed to the lower of two potential values, rather than the even one. Only the signing code was changed though, the (for now unused) verification code wasn't adapted.

* / Inline signature serializerPieter Wuille2013-09-281-45/+101
|/ | | | | | | | | | | | | | | | Instead of building a full copy of a CTransaction being signed, and then modifying bits and pieces until its fits the form necessary for computing the signature hash, use a wrapper serializer that only serializes the necessary bits on-the-fly. This makes it easier to see which data is actually being hash, reduces load on the heap, and also marginally improves performances (around 3-4us/sigcheck here). The performance improvements are much larger for large transactions, though. The old implementation of SignatureHash is moved to a unit tests, to test whether the old and new algorithm result in the same value for randomly-constructed transactions.

* | Only create signatures with even S, and verification mode to check.Pieter Wuille2013-08-161-9/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To fix a minor malleability found by Sergio Lerner (reported here: https://bitcointalk.org/index.php?topic=8392.msg1245898#msg1245898) The problem is that if (R,S) is a valid ECDSA signature for a given message and public key, (R,-S) is also valid. Modulo N (the order of the secp256k1 curve), this means that both (R,S) and (R,N-S) are valid. Given that N is odd, S and N-S have a different lowest bit. We solve the problem by forcing signatures to have an even S value, excluding one of the alternatives. This commit just changes the signing code to always produce even S values, and adds a verification mode to check it. This code is not enabled anywhere yet. Existing tests in key_tests.cpp verify that the produced signatures are still valid.
