wsc-crypto-ts

PoC of cryptographic utility functions for WoltLab Suite Core, implemented in TypeScript.

Overview

This project provides cryptographic helper functions, including:

• Creating secure signatures based on the Keyed-Hash Message Authentication Code (HMAC) algorithm.
• Hexadecimal encoding and decoding without cache-timing leaks.

Installation

npm install wsc-crypto-ts

Usage

Creating a Signed String

import { createSignedStringForSession } from 'wsc-crypto-ts';

// Your session ID and secret
const sessionID = 'your-session-id';
const secret = 'your-secret-key';

// Create a signed string
const signedString = createSignedStringForSession(sessionID, secret);

console.log('Signed String:', signedString);

Verifying a Signed String

import { CryptoUtil } from 'wsc-crypto-ts';

// Initialize CryptoUtil with your secret
const cryptoUtil = new CryptoUtil(secret);

// Verify and decode the signed string
const decodedValue = cryptoUtil.verifySignedString(signedString);

if (decodedValue !== null) {
  console.log('Decoded Value:', decodedValue.toString('utf8'));
} else {
  console.error('Invalid signature!');
}
