2014-03-18Add licenses for tests and test dataWladimir J. van der Laan
- Add license headers to source files (years based on commit dates) in `src/test` as well as `qa` - Add `README.md` to `src/test/data` specifying MIT license Fixes #3848
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.
2013-09-16included-tests: generate binary data from test files for inclusion into test ↵Cory Fields
binaries This change moves test data into the binaries rather than reading them from the disk at runtime. Advantages: - Tests become distributable - Cross-compile friendly. Build on one machine and execute in an arbitrary location on another. - Easier testing for backports. Users can verify that tests pass without having to track down corresponding test data. - More trustworthy test results and easier quality assurance as tests make fewer assumptions about their environment. - Tests could theoretically run at client/daemon startup and exit on failure. Disadvantages: - Required 'hexdump' build-dependency. This is a standard bsd tool that should be usable everywhere. It is likely already installed on all build-machines. - Tests can no longer be fudged after build by altering test-data.
2013-08-16Only create signatures with even S, and verification mode to check.Pieter Wuille
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.
