Nuxor Documentation

Nuxor is a privacy-focused platform providing end-to-end encrypted storage, anonymous file sharing, zero-knowledge proofs, and secure communication channels.

Quick Start

Get started with Nuxor in just a few steps. No account required for most features.

Overview

The Encrypted Vault provides secure, zero-knowledge storage for your sensitive files. All encryption occurs client-side using AES-256-GCM, ensuring that your data remains private even from us.

Key Features

• Zero-Knowledge Encryption

  Files are encrypted before upload. We never see your data.

• Client-Side Key Derivation

  Keys derived from your passphrase using PBKDF2, never leaving your device.

• AES-256-GCM Encryption

  Industry-standard authenticated encryption.

Technical Details

// Key derivation
const key = await crypto.subtle.deriveKey(
  { name: "PBKDF2", salt, iterations: 100000, hash: "SHA-256" },
  baseKey,
  { name: "AES-GCM", length: 256 },
  false,
  ["encrypt", "decrypt"]
);

// Encryption
const iv = crypto.getRandomValues(new Uint8Array(12));
const ciphertext = await crypto.subtle.encrypt(
  { name: "AES-GCM", iv },
  key,
  plaintext
);

Overview

Share files securely without revealing your identity. No account required, no tracking, and files are automatically deleted after expiration.

How to Share Files

What are Zero-Knowledge Proofs?

Zero-Knowledge Proofs (ZKPs) allow you to prove something is true without revealing the underlying data. With ZK File Proofs, you can prove file ownership, integrity, or existence at a specific time without exposing the actual content.

Use Cases

How It Works

// Generate cryptographic hash of file
const hash = await crypto.subtle.digest("SHA-256", fileBuffer);

// Create timestamped proof
const proof = {
  hash: arrayBufferToHex(hash),
  timestamp: Date.now(),
  signature: await sign(hash, privateKey)
};

// Verify proof (anyone can do this)
const isValid = await verify(proof.hash, proof.signature, publicKey);

Overview

Create ephemeral, end-to-end encrypted communication channels. Messages are encrypted in your browser before sending, and only participants with the shared secret can decrypt them.

Security Features

• End-to-End Encryption

  All messages encrypted client-side using AES-256-GCM.

• Shared Secret Authentication

  Only users with the passphrase can join and read messages.

• Ephemeral Messages

  Messages are not stored permanently on servers.

Getting Started

// Derive key from shared secret + room ID
const key = await deriveKeyFromPassphrase(secret, roomId);

// Encrypt message before sending
const iv = crypto.getRandomValues(new Uint8Array(12));
const ciphertext = await crypto.subtle.encrypt(
  { name: "AES-GCM", iv },
  key,
  new TextEncoder().encode(message)
);

// Send encrypted payload
await send({ iv, ciphertext });

Security Model

Nuxor is built with a zero-trust security model. All sensitive operations happen client-side, and we never have access to your unencrypted data.
