Reduce API surface of tagged wrapped hash types
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.

Documentation

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.
