Merge rust-bitcoin/rust-secp256k1#603: Add toolchain matrix to WASM job 
77808b7d83 WIP: Add toolchain matrix to job (Tobin C. Harding)

Pull request description:

  Recently I changed CI to use the dtolnay runner and in doing so introduced a regression (knowingly) whereby we only ran the WASM tests with the stable toolchain.

  Run the WASM tests with multiple toolchains
  - stable
  - beta
  - 1.48.0
  - nightly

Full documentation

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 1.48.0.

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.

Benchmarks

We use a custom Rust compiler configuration conditional to guard the bench mark code. To run the bench marks use: RUSTFLAGS='--cfg=bench' cargo +nightly bench --features=recovery.

A note on non_secure_erase

This crate's secret types (SecretKey, KeyPair, SharedSecret, Scalar, and DisplaySecret) have a method called non_secure_erase that attempts to overwrite the contained secret. This method is provided to assist other libraries in building secure secret erasure. However, this library makes no guarantees about the security of using non_secure_erase. In particular, the compiler doesn't have any concept of secrets and in most cases can arbitrarily move or copy values anywhere it pleases. For more information, consult the zeroize documentation.

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.
