Tobin C. Harding 4e44abc2e0 Bump version to v0.23.1 
We just applied a hot fix to the 0.23.0 released code to fix the
features enabled in `rand` when our "rand-std" feature is enabled. This
requires a bump of the patch version for release.

Bump the version and add a changelog entry.

rust-secp256k1

rust-secp256k1 is a wrapper around libsecp256k1, a C library by Pieter Wuille for producing ECDSA signatures using the SECG curve secp256k1. This library

  • exposes type-safe Rust bindings for all libsecp256k1 functions
  • implements key generation
  • implements deterministic nonce generation via RFC6979
  • implements many unit tests, adding to those already present in libsecp256k1
  • makes no allocations (except in unit tests) for efficiency and use in freestanding implementations

Contributing

Contributions to this library are welcome. A few guidelines:

  • Any breaking changes must have an accompanied entry in CHANGELOG.md
  • No new dependencies, please.
  • No crypto should be implemented in Rust, with the possible exception of hash functions. Cryptographic contributions should be directed upstream to libsecp256k1.
  • This library should always compile with any combination of features on Rust 1.41.1.

Githooks

To assist devs in catching errors before running CI we provide some githooks. If you do not already have locally configured githooks you can use the ones in this repository by running, in the root directory of the repository:

git config --local core.hooksPath githooks/

Alternatively add symlinks in your .git/hooks directory to any of the githooks we provide.

Fuzzing

If you want to fuzz this library, or any library which depends on it, you will probably want to disable the actual cryptography, since fuzzers are unable to forge signatures and therefore won't test many interesting codepaths. To instead use a trivially-broken but fuzzer-accessible signature scheme, compile with --cfg=fuzzing in your RUSTFLAGS variable.

Note that cargo hfuzz sets this config flag automatically.
