lwecrypt

A collection of auth-related utilities, including:

• lwecrypt/lwe: Enhanced encryption using AES with quantum key distribution and HMAC.

Overview

lwecrypt is a modern approach to encryption that leverages the hardness of certain lattice problems to ensure security. It includes advanced encryption utilities designed for secure data transmission

Features

• Encryption: Encrypt messages using a generated public key or symmetric key.
• Decryption: Decrypt ciphertexts using the secret key.
• Quantum Key Distribution: Simulated quantum key distribution for secure key exchange.
• HMAC: Ensure data integrity and authenticity using HMAC.
• Salt Generation: Generate a random salt of a specified number of bytes..

Every module works in any environment, including Node.js, Cloudflare Workers, Deno, and Bun.

Installation

npm i lwecrypt
pnpm add lwecrypt
yarn add lwecrypt
bun i lwecrypt

Example usage:

async (recommended)

Importing the Library

import { generateSalt, deriveKey, encrypt, decrypt } from "lwecrypt";

Generate a salt:

const salt = await generateSalt(16);

Derive a key from a password:

const key = await deriveKey(myPlaintextPassword, salt);

Encrypt a message:

const { iv, ciphertext, hmac } = await encrypt(myPlaintextMessage, key);

Decrypt a message:

const decryptedMessage = await decrypt(iv, ciphertext, hmac, key);

import { Encryption } from "lwecrypt";

const myPlaintextPassword  = 's0/\/\P4$$w0rD';
const saltRounds  = 12;
const key = decrypt(myPlaintextPassword, saltRounds);
const someOtherPlaintextPassword  = 'This is a secret message';

To encrypt a password:

const { iv, ciphertext, hmac } = await encrypt(someOtherPlaintextPassword, key);
// Store hashedPassword in your database

To verify a password:

const isPasswordCorrect = await decrypt(iv, ciphertext, hmac, key);
// isPasswordCorrect will be true if the passwords match
