pe-library

pe-library provides parsing and generating Portable Executable (known as Windows Executables) binaries.

Usage

import * as PE from 'pe-library';
import * as fs from 'fs';

// load and parse data
let data = fs.readFileSync('MyApp.exe');
// (the Node.js Buffer instance can be specified directly to NtExecutable.from)
let exe = PE.NtExecutable.from(data);

// get section data
let exportSection = exe.getSectionByEntry(PE.Format.ImageDirectoryEntry.Export);
// read binary data stored in exportSection.data ...
// to write binary: use exe.setSectionByEntry

// write to buffer
let newBin = exe.generate();
fs.writeFileSync('MyApp_modified.exe', new Buffer(newBin));
