# 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](https://docs.rs/bitcoin_hashes/)
## Minimum Supported Rust Version (MSRV)
This library should always compile with any combination of features on **Rust 1.29**.
However, due to some dependencies breaking their MSRV in patch releases, you may
need to pin these deps explicitly, e.g. with the following commands
```
cargo generate-lockfile
cargo update -p serde_json --precise "1.0.39"
```
## Contributions
Contributions are welcome, including additional hash function implementations.
