# 🚀 How to Use nofuture.go
This guide explains how to use `nofuture.go` in practice with a mainstream chat application.
---
## ⚙️ Requirements
- Modern browser (Chrome, Firefox, Brave, etc.)
- JavaScript enabled
- Optional: virtual keyboard enabled for secure passphrase input
---
## 🧪 Step-by-step Example
### 1. Open `nofuture.go` in one browser tab
> Visit: `https://safecomms.virebent.art`
You will see the interface for starting a new secure session.
---
### 2. Open your chat app in another tab
Use any web-based messaging platform:
- Signal Web
- Telegram Web
- WhatsApp Web
- Email client (optional)
---
### 3. Generate a Session ID
In `nofuture.go`, click **"Generate Session ID"**.
This creates a **post-quantum key pair**, generates a random nonce, and bundles them into your personal **Session ID**.
You can think of your `Session ID` like a **temporary public key**: it tells the other party how to encrypt messages for you.
---
### 4. Share Your Session ID
Copy your Session ID and paste it into your chat app.
Send it to your conversation partner. They will import it into their own instance of `nofuture.go`.
> ✅ Session IDs contain **no sensitive private key data** — they are safe to transmit over standard channels.
---
### 5. Synchronize Sessions
This is the **core step**:
When the other user imports your Session ID, their instance uses it to derive a **shared secret** and bind their session to yours.
🔄 Once both users are synchronized:
- Messages can be encrypted asymmetrically using XChaCha and the shared key
- The session is protected against MITM (with optional signature validation)
- The encrypted messages are now meaningful only to those inside the session
> Without synchronization, decryption will fail.
> With it, communication is seamless, secure, and ephemeral.
---
### 6. Start exchanging encrypted messages
- You write your message in `nofuture.go`
- It’s encrypted and output as ciphertext
- You copy that into your chat app
- Your contact copies the ciphertext back into their `nofuture.go`, which decrypts it
---
### 7. End Session when done
Once the conversation is finished:
- Click “End Session”
- All keys are destroyed securely in memory
- Even if the ciphertext remains in the chat, it can never be decrypted again
> 💣 Your private key is never written to disk and is irreversibly destroyed.
---
## 🧼 Security Notes
- Session data is stored only in encrypted memory
- `memguard` prevents access even from root processes or dump tools
- Virtual keyboard bypasses system-level keyloggers
---
Enjoy your ephemeral, post-quantum privacy ✊
