The code in `siphash24` was obtaining the pointer in buffer at offset by accessing an element at that offset instead of accessing a range or simply computing the offset of the pointer from the start. This is UB because one canot access past `T` even if the allocation is known to be large enough. This change fixes it by using a range and also replaces complicated code with simpler use of `from_le_bytes`. It's quite likely that this can be improved further, possibly even removing the `unsafe` without speed penalty but it's a larger task that's not a priority right now. |

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 ancillary 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 1.63.0.
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.
