Recently we made it so that wrapper types created with `hash_newtype` were not general purpose hash types i.e., one could not easily hash arbitrary data into them. We would like to do the same for tagged wrapped hash types. In `hashes` do: - Create a new macro `sha256t_tag` that does just the tag/engine stuff out of the `sha256t_hash_newtype` macro. - Deprecate the `sha256t_hash_newtype` macro. In `bitcoin` do: - Use a combination of `sha256t_tag` and `hash_newtype` to create tagged wrapped hash types. Note that we do not add private helper functions `engine` and `from_engine` to the tagged wrapper types as we do for legacy/segwit in `sighash`. Can be done later if wanted/needed. |

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
.
