## 🎯 Why VLT-CLI?

<table>
<tr>
<td width="50%" valign="top">

### ❌ Without VLT-CLI

```bash
# Your .env file (plain text)
DATABASE_URL=postgresql://admin:pass123@...
API_KEY=sk_live_abc123xyz789...
AWS_SECRET=wJalrXUtnFEMI/K7MDENG...

# Risks:
❌ Accidentally committed to Git
❌ Shared via Slack/Email
❌ Visible to anyone with file access
❌ No encryption at rest
❌ No audit trail
```

</td>
<td width="50%" valign="top">

### ✅ With VLT-CLI

```bash
# Encrypted vault (.vlt file)
�k�X�8�a�m�W�E�Z...
# Unreadable encrypted data

# Benefits:
✅ AES-256 military-grade encryption
✅ Master password protection
✅ Safe to commit to Git

# Install dependencies
pip install -r requirements.txt

# Verify installation
python main.py --version
```

- **Dependencies**: Automatically installed

---

## ⚡ Quick Start

### 1️⃣ Lock Your Secrets

Encrypt your `.env` file with a master password:

```bash
vlt lock .env --name production --description "Production API keys"
```

**What happens:**
1. 🔐 You create a strong master password
2. 🔒 File encrypted with AES-256
3. 💾 Saved as `.env.vlt` (safe to commit!)
4. 🗑️ Original `.env` can be deleted

### 2️⃣ Run Your Application (🌟 Most Secure!)

Execute commands with encrypted variables loaded **in memory only**:

```bash
# Node.js
vlt run --name production -- npm start

# Python
vlt run --name production -- python app.py

# Docker
vlt run --name production -- docker-compose up
```

**Magic:** Secrets are decrypted in RAM, injected into your app, and never written to disk!

### 3️⃣ Manage Vaults

```bash
# List all vaults
vlt list

┌──────────────┬─────────────────────┬────────────┬─────────────┐
│ Name         │ Description         │ Created    │ Last Access │
├──────────────┼─────────────────────┼────────────┼─────────────┤
│ production   │ Production API keys │ 2026-01-15 │ 2026-01-18  │
│ staging      │ Staging environment │ 2026-01-12 │ 2026-01-17  │
│ development  │ Local dev secrets   │ 2026-01-10 │ 2026-01-18  │
└──────────────┴─────────────────────┴────────────┴─────────────┘
```

### 4️⃣ Team Collaboration

```bash
# Add team member
vlt add-member --name production --email dev@company.com --role developer

# View team
vlt team --name production

# Check audit logs
vlt audit --limit 50
```

## 🔐 Security Best Practices

### ✅ DO's

- ✅ **Use strong passwords**: 16+ characters, mix of uppercase, lowercase, digits, symbols
- ✅ **Use** `vlt run` **command**: Most secure - memory-only decryption
- ✅ **Commit** `.vlt` **files**: They're encrypted and safe!
- ✅ **Store passwords in password manager**: 1Password, LastPass, Bitwarden
- ✅ **Rotate passwords every 90 days**: For production vaults
- ✅ **Enable audit logging**: Track all access
- ✅ **Use separate vaults**: dev, staging, production

### ❌ DON'Ts

- ❌ **Don't commit** `.env` **files**: Always in `.gitignore`
- ❌ **Don't share passwords via Slack/Email**: Use secure channels
- ❌ **Don't use weak passwords**: "password123" is not secure!
- ❌ **Don't share production passwords widely**: Limit access
- ❌ **Don't leave unlocked files around**: Delete after use
