* Increment MIT Licence copyright header year on files modified in 2016isle29832016-12-311-1/+1

* Get rid of nType and nVersionPieter Wuille2016-11-071-2/+2
| | | | | | | | | | | Remove the nType and nVersion as parameters to all serialization methods and functions. There is only one place where it's read and has an impact (in CAddress), and even there it does not impact any of the recursively invoked serializers. Instead, the few places that need nType or nVersion are changed to read it directly from the stream object, through GetType() and GetVersion() methods which are added to all stream classes.
* wallet: Get rid of LockObject and UnlockObject calls in key.hWladimir J. van der Laan2016-10-191-18/+9
| | | | | | | | | | | | Replace these with vectors allocated from the secure allocator. This avoids mlock syscall churn on stack pages, as well as makes it possible to get rid of these functions. Please review this commit and the previous one carefully that no `sizeof(vectortype)` remains in the memcpys and memcmps usage (ick!), and `.data()` or `&vec[x]` is used as appropriate instead of &vec.

* | Update key.cpp to use new libsecp256k1Pieter Wuille2015-05-041-1/+7
|/ | | | | | | | | | | | | | | libsecp256k1's API changed, so update key.cpp to use it. Libsecp256k1 now has explicit context objects, which makes it completely thread-safe. In turn, keep an explicit context object in key.cpp, which is explicitly initialized destroyed. This is not really pretty now, but it's more efficient than the static initialized object in key.cpp (which made for example bitcoin-tx slow, as for most of its calls, libsecp256k1 wasn't actually needed). This also brings in the new blinding support in libsecp256k1. By passing in a random seed, temporary variables during the elliptic curve computations are altered, in such a way that if an attacker does not know the blind, observing the internal operations leaks less information about the keys used. This was implemented by Greg Maxwell.
* Switch test case signing to RFC6979 extra entropyPieter Wuille2015-03-271-2/+1
| | | | | Instead of manually tweaking the deterministic nonce post-generation, pass the test case number in as extra entropy to RFC6979.
* allocators: split allocators and pagelockerCory Fields2015-03-201-1/+1
| | | | | Pagelocker is only needed for secure (usually wallet) operations, so don't make the zero-after-free allocator depend on it.

|/ | | | | | Fix a few warnings reported by Coverity. None of these is critical, but making sure that class fields are initialized can avoid heisenbugs.
* key.cpp: fail with a friendlier message on missing ssl EC supportAndrew Poelstra2014-06-031-0/+3
| | | | | | | | | | | | | | | | | | | | | Previously if bitcoind is linked with an OpenSSL which is compiled without EC support, this is seen as an assertion failure "pKey != NULL" at key.cpp:134, which occurs after several seconds. It is an esoteric piece of knowledge to interpret this as "oops, I linked with the wrong OpenSSL", and because of the delay it may not even be noticed. The new output is : OpenSSL appears to lack support for elliptic curve cryptography. For more information, visit https://en.bitcoin.it/wiki/OpenSSL_and_EC_Libraries : Initialization sanity check failed. Bitcoin Core is shutting down. which occurs immediately after attempted startup. This also blocks in an InitSanityCheck() function which currently only checks for EC support but should eventually do more. See #4081.
* remove CPubKey::VerifyCompact( ) which is never usedKamil Domanski2014-05-201-4/+0

* Also switch the (unused) verification code to low-s instead of even-s.Pieter Wuille2014-03-101-0/+3
| | | | | | | | 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.

* Cleanup code using forward declarations.Brandon Dahler2013-11-101-3/+5

Normalize QT_VERSION ifs where possible. Resolve some indirect dependencies as direct ones. Remove extern declarations from .cpp files.

* Compact serialization for scriptsPieter Wuille2012-10-201-2/+1
| | | | | | | | | | | Special serializers for script which detect common cases and encode them much more efficiently. 3 special cases are defined: * Pay to pubkey hash (encoded as 21 bytes) * Pay to script hash (encoded as 21 bytes) * Pay to pubkey starting with 0x02, 0x03 or 0x04 (encoded as 33 bytes) Other scripts up to 121 bytes require 1 byte + script length. Above that, scripts up to 16505 bytes require 2 bytes + script length.

* Refactor: split CKeyID/CScriptID/CTxDestination from CBitcoinAddressPieter Wuille2012-05-241-2/+23
| | | | | | | | | | | | | | | | | 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.
