Kapsule JS – Lightweight PQ-Ready Encryption Library

Kapsule JS is a JavaScript/TypeScript library offering a simplified, hybrid-friendly encryption layer built with Web Crypto APIs. Designed to mimic post-quantum workflows, it's a frontend-ready companion to Kapsule CLI.

---

🚀 Quickstart

npm install
npx tsx tests/test.ts

🔐 Features
RSA-OAEP encryption (placeholder for PQC)

Modular design (keygen, encrypt, decrypt)

Future-ready for WASM-based PQC engines

Clean TypeScript interface

🧪 Example

import { generateKeyPair, encrypt, decrypt } from "./src/crypto";

const { publicKey, privateKey } = await generateKeyPair();
const ciphertext = await encrypt(publicKey, "Hello from Kapsule JS!");
const plaintext = await decrypt(privateKey, ciphertext);

This SDK uses standard Web Crypto as a scaffold for future post-quantum modules (via WASM). It is not yet secure against quantum attacks.
