Martin Habovstiak 42d3ae05be Implement computing SHA256 in const context Computing hashes in const fn is useful for esily creating tags for `sha256t`. This adds `const fn` implementation for `sha256::Hash` and the algorithm for computing midstate of tagged hash in `const` context. Part of #1427		2023-04-02 01:35:12 +02:00

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.

Documentation

Minimum Supported Rust Version (MSRV)

This library should always compile with any combination of features on Rust 1.48.0.

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.
