Cryptus

Cryptus is a multi-language cryptography and hashing library designed to provide a simple and consistent interface for developers working with cryptographic operations across different programming languages.

Features

Encryption & Decryption: Simplify data protection with straightforward functions.
Key Derivation & Generation: Generate strong keys with Argon2 and PBKDF2.
Hashing & Secure Storage: Hash passwords and securely store sensitive data.
Modular Design: Use only what you need to keep your project lean.

Supported Algorithms

Cryptus currently supports the following cryptographic algorithms:

RSA – Asymmetric encryption and key generation
Argon2 – Memory-hard password hashing (Argon2id)
PBKDF2 – Password-based key derivation
AES – Symmetric encryption (AES-256)
Sha256 – Cryptographic hash function producing 256-bit fixed-size output

Installation

To install Cryptus, run:

npm i @ravoni4devs/libcryptus

To add Argon2 support:

npm i argon2-browser

# Then add this script to your HTML
<script src="node_modules/argon2-browser/dist/argon2-bundled.js"></script>

Usage

ES6 module

Here’s a simple AES encryption example:

import Cryptus from '@ravoni4devs/libcryptus'

const plainText = 'strongpass';
const cryptus = new Cryptus();
const passwordHex = await cryptus.pbkdf2({
  plainText: plainText,
  salt: '123456',
  length: 128  // 128 = 32 bits = max length supported to aes-gcm
})
console.log(passwordHex)  // 1498cccb3cab5e895d6912d78aef6ab2

const nonceHex = helpers.strToHex('12345678');
console.log(nonceHex)    // 3132333435363738

const cipherText = await cryptus.encryptAes({plainText, nonceHex, passwordHex});
console.log(cipherText)  // fd1ceaa8d7f03be768d410f07c017f3f7e62c8af6c9061cbaa0d

const decryptedText = await cryptus.decryptAes({cipherText, nonceHex, passwordHex});
console.log(decryptedText)
