# `Cartouche.Hash`
[🔗](https://github.com/zenhive/cartouche/blob/main/lib/cartouche/hash.ex#L1)

Keccak-256 helpers for hashing arbitrary binaries.

Returns either the 32-byte binary digest (`keccak/1`) or its unsigned
integer interpretation (`keccak_unsigned/1`).

## API Functions
| Function | Arity | Description | Param Kinds |
| --- | --- | --- | --- |
| `keccak_unsigned` | 1 | Hash a binary message with Keccak-256 and decode the digest as an unsigned integer. | `message: value` |
| `keccak` | 1 | Hash a binary message with Keccak-256. | `message: value` |

# `keccak`

```elixir
@spec keccak(binary()) :: <<_::256>>
```

Returns the keccak of the given binary message.

## Examples

  iex> use Cartouche.Hex
  iex> Cartouche.Hash.keccak("test")
  ~h[0x9C22FF5F21F0B81B113E63F7DB6DA94FEDEF11B2119B4088B89664FB9A3CB658]

# `keccak_unsigned`

```elixir
@spec keccak_unsigned(binary()) :: non_neg_integer()
```

Returns the keccak of the given binary message, as an unsigned.

## Examples

  iex> Cartouche.Hash.keccak_unsigned("test")
