2019-05-16Merge #14047: Add HKDF_HMAC256_L32 and method to negate a private keyWladimir J. van der Laan
8794a4b3ae4d34a4cd21a7dee9f694eef7726a4f QA: add test for HKDF HMAC_SHA256 L32 (Jonas Schnelli) 551d489416339dae8f9d896013cd060a21406e2b Add HKDF HMAC_SHA256 L=32 implementations (Jonas Schnelli) 3b64f852e400c552f031697d6a86829dc6e74bd6 QA: add test for CKey::Negate() (Jonas Schnelli) 463921bb649d644f79f9d7f0f96f10aa0d165f76 CKey: add method to negate the key (Jonas Schnelli) Pull request description: This adds a limited implementation of `HKDF` (defined by rfc5869) that supports only HMAC-SHA256 and length output of 32 bytes (will be required for v2 transport protocol). This PR also includes a method to negate a private key which is useful to enforce public keys starting with 0x02 (or 0x03) (a requirement for the v2 transport protocol). The new `CKey::Negate()` method is pretty much a wrapper around `secp256k1_ec_privkey_negate()`. Including tests. This is a subset of #14032 and a pre-requirement for the v2 transport protocol.

c01c065b9ded3399a6a480f15543827dd5e8eb4d Do not construct out-of-bound pointers in SHA512/SHA1/RIPEMD160 code (Pieter Wuille) Pull request description: This looks like an issue in the current SHA256/512 code, where a pointer outside of the area pointed to may be constructed (this is UB in theory, though in practice every supported platform treats pointers as integers). I discovered this while investigating #14580. Sadly, it does not fix it.

2dfe27517 Add ChaCha20 bench (Jonas Schnelli) 2bc2b8b49 Add ChaCha20 encryption option (XOR) (Jonas Schnelli) Pull request description: The current ChaCha20 implementation does not support message encryption (it can only output the keystream which is sufficient for the RNG). This PR adds the actual XORing of the `plaintext` with the `keystream` in order to return the desired `ciphertext`. Required for v2 message transport protocol.

f6ee177f7 Remove unused AES-128 code (practicalswift) Pull request description: Remove unused AES-128 code. As far as I can tell this AES-128 code has never been in use in the project (outside of testing/benchmarking). The AES-256 code is used in `CCrypter::Encrypt`/`CCrypter::Decrypt` (`src/wallet/crypter.cpp`). Trivia: 0.15% of the project's C++ LOC count (excluding dependencies) is trimmed off: ``` $ LOC_BEFORE=$(git grep -I "" HEAD~1 -- "*.cpp" "*.h" ":(exclude)src/leveldb/" ":(exclude)src/secp256k1/" ":(exclude)src/univalue/" | wc -l) $ LOC_AFTER=$(git grep -I "" -- "*.cpp" "*.h" ":(exclude)src/leveldb/" ":(exclude)src/secp256k1/" ":(exclude)src/univalue/" | wc -l) $ bc <<< "scale=4; ${LOC_AFTER}/${LOC_BEFORE}" .9985 ``` :-) Tree-SHA512: 9588a3cd795a89ef658b8ee7323865f57723cb4ed9560c21de793f82d35e2835059e7d6d0705e99e3d16bf6b2a444b4bf19568d50174ff3776caf8a3168f5c85

Fix this. Note that these instruction sets are only available on CPUs that support 64-bit mode as well, so it is only beneficial in the (perhaps unlikely) scenario where a 64-bit CPU is running a 32-bit Bitcoin Core binary.
