# Overview

A broken code signature is often worse than no signature, so it can be desirable to remove a signature.

This package can remove code signatures from PE binaries.

# Usage

Just pass an `ArrayBuffer` or an object that is a view of an `ArrayBuffer` to the `signatureGet` and `signatureSet` functions.

```js
import {readFile, writeFile} from 'node:fs/promises';
import {signatureGet, signatureSet} from 'portable-executable-signature';

const data = await readFile('pe-binary.exe');
const signature = signatureGet(data);
console.log('signature:', signature);
const unsigned = signatureSet(data, null);
console.log('unsigned:', unsigned);
await writeFile('pe-binary-unsigned.exe', Buffer.from(unsigned));
```
