Wladimir J. van der Laan c4f7bb5d72 Merge #14047: Add HKDF_HMAC256_L32 and method to negate a private key ... 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. ACKs for commit 8794a4: Tree-SHA512: 5341929dfa29f5da766ec3612784baec6a3ad69972f08b5a985a8aafdae4dae36f104a2b888d1f5d1f33561456bd111f960d7e32c2cc4fd18e48358468f26c1a		2021-08-10 23:55:56 +03:00
