Security Architecture

Your credentials never touch the cloud.

Unlike online password managers that store your database on remote servers, Umbral keeps your vault encrypted strictly on your physical SSD using AES-256-GCM.

✓

PBKDF2 Key Derivation

310,000 SHA-256 hashing iterations with cryptographically random salt.

✓

Instant Memory Sanitation

Node buffers and PowerShell credential copies are overwritten with zeroes immediately after autofill.

✓

100% Vanguard Safe

Umbral operates exclusively on the desktop login window prior to game execution and never hooks into game memory.

// crypto.ts AES-256-GCM (v1.1)

const ALGORITHM = 'aes-256-gcm';
const PBKDF2_ITERATIONS = 310_000;
const PBKDF2_DIGEST = 'sha256';

// Derive encryption key from Master Password
export function deriveKey(masterPassword, saltHex) {
  const salt = Buffer.from(saltHex, 'hex');
  return pbkdf2Sync(masterPassword, salt, PBKDF2_ITERATIONS, 32, PBKDF2_DIGEST);
}

// Zero-out memory buffer after usage
export function wipeBuffer(buf) {
  buf.fill(0);
}

Frequently Asked Questions

Got questions? We've got answers.

Can I get banned by Riot Games or Vanguard for using Umbral?

No. Umbral does not inject into game processes, alter game files, or read game memory. It interacts strictly with the standard Windows desktop Riot Client login form using standard Win32 keyboard events before League of Legends or VALORANT even opens.

Does Umbral work on Windows 10 and Windows 11?

Yes! Umbral is built on modern 64-bit Electron and native Win32 APIs that are 100% compatible with both Windows 10 (version 19041+) and Windows 11 out of the box.

Are my passwords sent to any remote server?

Never. Your passwords and credentials are encrypted strictly on your local PC using AES-256-GCM. Umbral has zero telemetry, zero analytics tracking, and no external password backend.

How do I access the floating overlay?

The overlay attaches automatically whenever you focus the Riot Client. You can also manually toggle the overlay anytime using the global keyboard shortcut Ctrl + Shift + O.
