XXVault – Secure Messenger App

**XXVault** (stylized as **xxvaulx**) is a cross-platform secure messenger application designed to provide robust **end-to-end encryption** for all your digital communications. It focuses on ensuring privacy by encrypting messages before they are sent and decrypting them only for the intended recipient, seamlessly integrating with popular social media platforms.

✨ Key Features & Security Focus

End-to-End Encryption (E2EE)

Utilizes strong cryptographic algorithms, likely **AES-256**, to ensure messages are encrypted from sender to receiver, making them unreadable to third parties.

Social Media Integration

Seamlessly integrate with popular social media platforms through **copy-paste functionality** or automated message handling via browser extensions.

Cross-Platform Availability

Designed for a broad reach, with a core application complemented by a **Microsoft Edge extension** for desktop users.

Intuitive Encryption/Decryption

A simple and intuitive user interface allows for easy **encryption and decryption** of text before sharing or after receiving messages.

Secure Local Storage

Securely stores encryption keys and user preferences locally, ensuring that sensitive data remains on the user's device.

User-Friendly Interface

Designed with a clean and modern UI, making the complex process of encryption accessible and easy for all users.

// Pseudocode for XXVault Encryption Process
function encryptMessage(plaintext, secretKey) {
    const iv = generateRandomIV();
    const encryptedData = AES_Encrypt(plaintext, secretKey, iv);
    return base64Encode(iv + encryptedData); // IV prepended for decryption
}

function decryptMessage(ciphertext, secretKey) {
    const decodedData = base64Decode(ciphertext);
    const iv = extractIV(decodedData);
    const encryptedData = extractEncryptedData(decodedData);
    return AES_Decrypt(encryptedData, secretKey, iv);
}
