Recently we made the hash engine fields pub crate so that `sha512_256` could construct a hash engine with different constants. We can make the code slightly cleaner by adding a pub crate constructor and making the fields private again. Idea from Kixunil: https://github.com/rust-bitcoin/rust-bitcoin/pull/1413#pullrequestreview-1197207593 |

Bitcoin Hashes Library
This is a simple, no-dependency library which implements the hash functions needed by Bitcoin. These are SHA1, SHA256, SHA256d, SHA512, and RIPEMD160. As an ancilliary thing, it exposes hexadecimal serialization and deserialization, since these are needed to display hashes anway.
Minimum Supported Rust Version (MSRV)
This library should always compile with any combination of features on Rust 1.48.0.
To build with the MSRV you will need to pin serde (if you have either the serde or the
schemars feature enabled)
# serde 1.0.157 uses syn 2.0 which requires edition 2021
cargo update -p serde --precise 1.0.156
before building. (And if your code is a library, your downstream users will need to run these commands, and so on.)
Contributions
Contributions are welcome, including additional hash function implementations.
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.
Running 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.
