Development of this library has now been moved over to the
rust-bitcoin repository (see rust-bitcoin/src/hashes).
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.
This library should always compile with any combination of features on Rust 1.41.1.
The one exception is the schemars feature which has no MSRV and should not be used
by users who expect stability from their libraries.
Contributions are welcome, including additional hash function implementations.
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.
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.
