Package for reading and writing PE code signatures

Overview

A broken code signature is 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.

import fs from 'fs';
import {
	signatureGet,
	signatureSet
} from 'portable-executable-signature';

const data = fs.readFileSync('pe-binary.exe');
const signature = signatureGet(data);
console.log('signature:', signature);
const unsigned = signatureSet(data, null);
console.log('unsigned:', unsigned);
fs.writeFileSync('pe-binary-unsigned.exe', Buffer.from(unsigned));
