2014-06-03key.cpp: fail with a friendlier message on missing ssl EC supportAndrew Poelstra
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.
2014-05-20remove CPubKey::VerifyCompact( ) which is never usedKamil Domanski
2014-03-10Also switch the (unused) verification code to low-s instead of even-s.Pieter Wuille
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.

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.
2013-10-28fix wrong memcmp() usage in CKey::operator==Philip Kaufmann
- add a check for CKey::size() of a and b (size can be 0 or 32) - change the fixed value in memcmp() to use a.size() instead - fixes #3090

2012-10-20Compact serialization for scriptsPieter Wuille
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.

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.

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.
