Open-Source Isn’t a Buzzword - It’s Our Battle Cry Against Closed Doors

In a world where Big Tech treats your data like a vending machine for ads and surveillance, open-source is the ultimate fuck-you to opacity. It’s not just code you can read; it’s code you can trust because anyone can audit it. Ellipticc Drive isn’t hiding behind proprietary walls, we’re flinging our doors wide open on GitHub. Every line of our frontend, from the sleek Next.js UI to the crypto guts encrypting your files, is there for you to fork, fix, and fortify.

Why does this matter? Closed-source tools like Dropbox or Google Drive? They’re black boxes. You upload a file, and poof, it’s scanned, profiled, and monetized without your say-so. Bugs fester in secret. Backdoors lurk. With Ellipticc, transparency is our default. Our repo at github.com/ellipticc/drive-frontend isn’t some half-assed side project; it’s the beating heart of a zero-knowledge platform where you hold the keys, literally.

Axiom
Open-source = Auditable trust.

No more blind faith in “we promise it’s secure.” Peek under the hood, contribute, or deploy your own instance.

We’re licensed under MIT, fork it, build on it, make it yours. Contributions? Pull requests welcome, but let’s keep it privacy-first: no telemetry, no bloat. Our community guidelines? Simple: Be bold, be rigorous, be respectful. In 2025, with quantum clouds looming, open-source isn’t optional, it’s oxygen for innovation.

The Repo Breakdown: Where the Magic Happens

Our frontend repo is a lean, mean Next.js machine built for speed and security. No bullshit dependencies; we stick to what works. Here’s the high-level map:

/src/app: The React/Next.js core, pages for dashboard, upload, sharing. Hydrates client-side for that buttery feel, but SSR for SEO and cold starts. /src/components: Reusable UI blocks, components, pages… These are where encryption hooks into the UX. /src/lib: The brains. Utils for crypto ops, file chunking, and API calls. This is your deep-dive destination. /src/hooks: Custom React hooks for file operations and crypto management. /public: Assets, icons, not so important stuff.

But let’s cut to the chase: You’re here for the crypto. Ellipticc isn’t slapping on some off-the-shelf AES; we’re wielding NIST-approved post-quantum algorithms to future-proof your shit. Dive in with us.

Tip
Fork us. Break us. Make us better.

github.com/ellipticc/drive-frontend, your move.

E2EE 101: Your Files, Your Castle - We Can’t Even Peek

End-to-end encryption (E2EE) means one thing: Your data is gibberish to everyone but you. Not us, not hackers, not quantum overlords. We use a hybrid system: Symmetric XChaCha20-Poly1305 for bulk file encryption (fast as hell for gigabytes), wrapped in asymmetric PQC keys for secure key exchange. Zero-knowledge proof? We store nothing that could decrypt your vault. Your master key? It lives in your browser’s secure session/localstorage.

Here’s the flow, bold and unbreakable:

Key Generation: On signup, your browser spits out a Kyber keypair (PQC key encapsulation) and a Dilithium signing key. No server touch, pure client-side. File Prep: Chunk your file (say, 1MB pieces for resumable uploads). Each chunk gets a random XChaCha20-Poly1305 key. Encrypt & Seal: XChaCha20-Poly1305-encrypt the chunk, then encapsulate the XChaCha20-Poly1305 key with your public Kyber. Sign the envelope with Dilithium. Upload: Encrypted blobs hit our servers. Metadata? Minimal and anonymized (Tor helps here). Decrypt: Download, unwrap with your private keys. Done. We see noise.

Our servers are completely blind to your data. They only store essential metadata required for functionality: file type, size, upload date, and a checksum for integrity. No filenames, no folder structures, no content previews, nothing that could compromise your privacy.

This isn’t theoretical, it’s battle-tested in /src/lib/crypto.ts. First, a strong encryption key is derived from your password using Argon2id, a memory-hard function that resists brute-force attacks. For example, with password “mySecurePass123” and salt “abcd1234”, you get a derived key like “a1b2c3d4…”. This ensures even weak passwords become strong keys.

src/lib/crypto.ts
import { argon2id } from 'hash-wasm';


// Derive encryption key from password using Argon2id
export async function deriveEncryptionKey(password: string, salt: string): Promise<Uint8Array> {
  const saltBytes = Uint8Array.from(atob(salt), c => c.charCodeAt(0));


  const hash = await argon2id({
    password: password,
    salt: saltBytes,
    parallelism: 1,
    iterations: 2,
    memorySize: 19456,
    hashLength: 32,
    outputType: 'binary'
  });


  return hash;
}


// Example: deriveEncryptionKey("password123", "YWJjZDEyMzQ=") => "089d374d43c9808295548633e856ece6b417d27948484291f9559178f60188b0" - Weak password? Argon2id turns it into crypto gold.
Danger
Use Strong Passwords!

Even with Argon2id, weak passwords can be cracked. Always use long, complex passwords with a mix of characters, numbers, and symbols.

Robust, right? All keypairs generated client-side with no server pings. Your keys stay yours, encrypted with Argon2id-derived masters. We leverage Web Crypto API and noble libraries for blazing performance, hardware acceleration on TPM or Secure Enclave baked in.

Post-Quantum Crypto: Quantum-Proofing Your Digital Vault

Quantum computers aren’t sci-fi anymore. Shor’s algorithm could crack RSA/ECDSA like a walnut by 20301. Enter PQC: Algorithms that laugh at qubits. Ellipticc bets big on NIST’s standards, Kyber for key exchange (replaces Diffie-Hellman), Dilithium for signatures (bye-bye ECDSA)2.

Why these?

Kyber: Lattice-based KEM (Key Encapsulation Mechanism). Encapsulate a symmetric key into a ciphertext that’s tiny and fast. Even if a quantum box Grover-attacks it, the security margins hold. Dilithium: Also lattice-based, for non-repudiation. Sign your file hashes so we know it’s you, without exposing you to forgery.

In code, file encryption looks like this (from /src/lib/crypto.ts):

src/lib/crypto.ts - Encryption & Signing
import { xchacha20poly1305 } from '@noble/ciphers/chacha';
import { ml_kem768 } from '@noble/post-quantum/ml-kem.js';
import { ml_dsa65 } from '@noble/post-quantum/ml-dsa.js';
import { sign as ed25519Sign } from '@noble/ed25519';


// Encrypt data with XChaCha20-Poly1305
export function encryptData(data: Uint8Array, key: Uint8Array): {
  encryptedData: string;
  nonce: string;
} {
  // Generate random 24-byte nonce
  const nonce = new Uint8Array(24);
  crypto.getRandomValues(nonce);


  // Encrypt using XChaCha20-Poly1305
  const encrypted = xchacha20poly1305(key, nonce).encrypt(data);


  return {
    encryptedData: uint8ArrayToBase64(encrypted),
    nonce: uint8ArrayToBase64(nonce)
  };
}


// Sign manifest with Ed25519 and Dilithium, encapsulate CEK with Kyber
export async function signAndEncryptManifest(manifestJson: string, keys: any, cek: Uint8Array) {
  const manifestBytes = new TextEncoder().encode(manifestJson);
  const { sha512 } = await import('@noble/hashes/sha2.js');
  const manifestHash = sha512(manifestBytes);


  // Sign with Ed25519
  const ed25519Signature = await ed25519Sign(new Uint8Array(manifestHash), keys.ed25519PrivateKey);
  const manifestSignatureEd25519 = btoa(String.fromCharCode(...new Uint8Array(ed25519Signature)));


  // Sign with Dilithium
  const dilithiumSignature = ml_dsa65.sign(keys.dilithiumPrivateKey, new Uint8Array(manifestHash));
  const manifestSignatureDilithium = btoa(String.fromCharCode(...new Uint8Array(dilithiumSignature)));


  // Encapsulate CEK with Kyber
  const kyberPublicKeyBytes = hexToUint8Array(keys.kyberPublicKey);
  const kyberEncapsulation = ml_kem768.encapsulate(kyberPublicKeyBytes);
  const kyberSharedSecret = new Uint8Array(kyberEncapsulation.sharedSecret);
  const kyberCiphertext = new Uint8Array(kyberEncapsulation.cipherText);


  // Encrypt CEK with Kyber shared secret
  const cekEncryption = encryptData(cek, kyberSharedSecret);


  return {
    manifestSignatureEd25519,
    manifestSignatureDilithium,
    kyberCiphertext: uint8ArrayToBase64(kyberCiphertext),
    cekEncryption
  };
}

Boom, chunk secured. Upload that blob, and quantum threats bounce off. Performance? Kyber ops clock under 10ms on mid-range hardware. We benchmarked it: Encrypting a 1GB file? Under 5 seconds client-side.

Note
Quantum’s coming. Are you ready?

RSA dies tomorrow. Kyber lives forever. Ellipticc future-proofs without the FUD.

Zero-Knowledge: We Know Nada, Not even your password hash

Zero-knowledge means we can’t decrypt jack. Your private keys never touch our servers. File listings? Encrypted indexes only you can parse. Sharing? Ephemeral links with time-bound Dilithium sigs, no central revocation needed.

Check this OPAQUE auth implementation for secure password-based authentication (/src/lib/opaque.ts):

src/lib/opaque.ts
'use client';
import * as opaque from '@serenity-kit/opaque';


const API_BASE_URL = 'https://drive.ellipticc.com/api/v1';


async function apiCall(endpoint: string, data: any): Promise<any> {
  const response = await fetch(`${API_BASE_URL}${endpoint}`, {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify(data),
    credentials: 'include',
  });
  const result = await response.json();
  if (!response.ok) throw new Error(result.error || `HTTP ${response.status}`);
  return result;
}


export class OPAQUE {
  static async register(password: string, email: string, name: string): Promise<any> {
    await opaque.ready;
    const { clientRegistrationState, registrationRequest } = opaque.client.startRegistration({ password });
    const regReqBase64 = Buffer.from(registrationRequest).toString('base64');


    const { registrationResponse } = await apiCall('/auth/opaque/register/process', { email, registrationRequest: regReqBase64 });


    const { registrationRecord } = opaque.client.finishRegistration({
      clientRegistrationState,
      registrationResponse,
      password,
    });
    const regRecBase64 = Buffer.from(registrationRecord).toString('base64');


    return await apiCall('/auth/opaque/register/finish', { email, name, registrationRecord: regRecBase64 });
  }


  static async login(password: string, email: string): Promise<any> {
    await opaque.ready;
    const { clientLoginState, startLoginRequest } = opaque.client.startLogin({ password });
    const startReqBase64 = Buffer.from(startLoginRequest).toString('base64');


    const { loginResponse, sessionId } = await apiCall('/auth/opaque/login/process', { email, startLoginRequest: startReqBase64 });


    const { finishLoginRequest, sessionKey } = opaque.client.finishLogin({
      clientLoginState,
      loginResponse,
      password,
    });
    const finishReqBase64 = Buffer.from(finishLoginRequest).toString('base64');


    return await apiCall('/auth/opaque/login/finish', { email, finishLoginRequest: finishReqBase64, sessionId });
  }
}


export default OPAQUE;

OPAQUE is a secure password-authenticated key exchange (PAKE) protocol that enables authentication without revealing passwords to servers, even in the event of a breach. It provides strong security guarantees against phishing, offline attacks, and server compromise.
