🔐 Encryptifier

Encryptifier is a lightweight Node.js package that provides easy-to-use encryption and decryption functions for text using standard algorithms like AES and DES — powered by crypto-js.

✨ Features

• 🔒 AES and DES encryption algorithms
• 🧠 Simple API for beginners
• ⚙️ Built on top of battle-tested crypto-js
• 📦 Lightweight and dependency-friendly

📦 Installation

npm install encryptifier

🚀 Usage

Basic Usage

const { encrypt, decrypt } = require("encryptifier");

// Encrypt a message
const encrypted = encrypt("Hello World", "aes", "my-secret-key");
console.log("Encrypted:", encrypted);

// Decrypt it back
const decrypted = decrypt(encrypted, "aes", "my-secret-key");
console.log("Decrypted:", decrypted);

📝 API Reference

encrypt(text, algorithm, key)

Encrypts the given text using the specified algorithm and key.

Parameters:

• text (string): The text to encrypt
• algorithm (string): The encryption algorithm ("aes" or "des")
• key (string): The encryption key

Returns: Encrypted string

decrypt(encryptedText, algorithm, key)

Decrypts the given encrypted text using the specified algorithm and key.

Parameters:

• encryptedText (string): The encrypted text to decrypt
• algorithm (string): The decryption algorithm ("aes" or "des")
• key (string): The decryption key (must match the encryption key)

Returns: Decrypted string

📋 Examples

Complete Example

const { encrypt, decrypt } = require("encryptifier");

const secretMessage = "Encrypt me, please!";
const key = "myPassword";

// AES encryption
const aesEncrypted = encrypt(secretMessage, "aes", key);
console.log("AES Encrypted:", aesEncrypted);
console.log("AES Decrypted:", decrypt(aesEncrypted, "aes", key));

// DES encryption
const desEncrypted = encrypt(secretMessage, "des", key);
console.log("DES Encrypted:", desEncrypted);
console.log("DES Decrypted:", decrypt(desEncrypted, "des", key));

Error Handling

const { encrypt, decrypt } = require("encryptifier");

try {
    const encrypted = encrypt("Hello World", "aes", "my-key");
    const decrypted = decrypt(encrypted, "aes", "my-key");
    console.log("Success:", decrypted);
} catch (error) {
    console.error("Encryption/Decryption failed:", error.message);
}

🔑 Supported Algorithms

| Algorithm | Description | |-----------|-------------| | aes | Advanced Encryption Standard (recommended) | | des | Data Encryption Standard |

⚠️ Security Notes

• Always use strong, unique keys for encryption
• AES is recommended over DES for better security
• Keep your encryption keys secure and never commit them to version control
• Consider using environment variables for sensitive keys
