advanced-cipher v1.0.0

Advanced Cipher

Overview

advanced-cipher is a sophisticated encryption library providing robust, multi-layer encryption with advanced key derivation techniques.

Features

• 256-bit encryption strength
• Multi-stage key derivation
• Complex bit-level transformations
• Secure encryption and decryption

Installation

npm install advanced-cipher

Usage

import AdvancedCipher from 'advanced-cipher';

// Create cipher instance with a secret key
const cipher = new AdvancedCipher('YourSecretKey123!@#');

// Encrypt message
const encrypted = cipher.encrypt('Hello, Secure World!');

// Decrypt message
const decrypted = cipher.decrypt(encrypted);

Security Details

• Bit Level: 256-bit
• Key Derivation: PBKDF2-inspired multi-iteration transformation
• Encryption Layers:
  1. XOR-based encryption
  2. Bit rotation
  3. Iteration-dependent obfuscation

API

new AdvancedCipher(secretKey, [iterations])

• secretKey (required): A string of at least 12 characters
• iterations (optional): Number of key derivation iterations (default: 10000)

encrypt(plaintext)

Encrypts the input text and returns a Base64 encoded string.

decrypt(ciphertext)

Decrypts the Base64 encoded ciphertext and returns the original plaintext.
