# Hash.create

Creates Node.js implementations of the [`Hash`](/api/Hash) primitives, without installing them.

Most callers want [`Engine.load`](/node/crypto/Engine/load) instead, which installs every implementation this entrypoint provides. Reach for this to take the `Hash` slot on its own, or to hold the implementation without touching the installed engine.

Node's `sha3-256` is not Ethereum Keccak256, so this engine deliberately omits `keccak256`. Any earlier override remains installed; otherwise Ox uses its default implementation.

## Imports

:::code-group
```ts [Named]
import { Hash } from 'ox/node'
```

```ts [Entrypoint]
import * as Hash from 'ox/node/Hash'
```
:::

## Examples

```ts twoslash
// @noErrors
import { Engine, Hash } from 'ox'
import * as NodeHash from 'ox/node/Hash'

Engine.set(await NodeHash.create())

Hash.sha256('0xdeadbeef')
```

## Definition

```ts
function create(): Promise<create.ReturnType>
```

**Source:** [src/node/Hash.ts](https://github.com/wevm/ox/blob/main/src/node/Hash.ts#L31)

## Return Type

An engine supplying the `Hash` slot.

`Promise<create.ReturnType>`
