# Engine

WASM implementations of ox's hash primitives, compiled from C.

Load it and hand the result to [`Engine.set`](/api/Engine/set). WASM must be compiled
asynchronously, so the `await` lives here -- every call afterwards is
synchronous.

:::note
Measured with `pnpm bench` against `@noble/hashes` 2.2.0, `keccak256` is
\~12-14x faster at every input size and `sha256` is ~1.1-3x faster. Numbers
vary by runtime -- re-measure on yours.

## Examples

```ts twoslash
// @noErrors
import { Hash } from 'ox'
import { Engine } from 'ox/wasm'

await Engine.load()

Hash.keccak256('0xdeadbeef')
```
