# 🛡️ SyckSec — Next-Gen Token Security

**Unbreakable • Unpredictable • Unrecognizable**  
SyckSec is a context-aware, multi-layer token security system designed to replace brittle, predictable authentication tokens like JWTs.  
It blends **encryption, obfuscation, visual camouflage, and adaptive intelligence** to create tokens that are **unreadable, unpredictable, and bound to the environment**.

## ❗ Problem
Authentication tokens in most applications suffer from:
- **Predictable structures** (e.g., JWT = header.payload.signature)
- **Weak context binding** (valid anywhere until expiry)
- **Replay vulnerabilities**
- **Lack of built-in anti-analysis**

Result:  
Tokens can be **stolen, replayed, or brute-forced offline**, leading to costly breaches in finance, healthcare, and government applications.

---

## 💡 Solution
SyckSec creates **multi-layer encrypted, context-bound tokens** with **dynamic obfuscation** and **visual camouflage**.

- **Unreadable**: AES-256 encryption + HMAC signature + per-layer random IVs.
- **Unpredictable**: Dynamic per-user obfuscation patterns rotate hourly.
- **Unrecognizable**: UUID-like visual formatting + checksum validation.
- **Context-Aware**: Tokens bound to device, location, and behavior.

## ⚙ Installation

```bash
# Python SDK
pip install sycksec
````

---

## 🚀 Quick Start

```python
from sycksec import SyckSec
import os

# Set secret (in production, use env vars)
os.environ['SYCKSEC_SECRET'] = 'your-secure-secret-32-chars-long!'

# Initialize client
sycksec = SyckSec()

# Custom recipe
custom_recipe = {
    "version": "custom_secure_v1",
    "pattern": [10, "core", 15, "core", 8],
    "charset": "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*()-_=+",
    "randomize_noise": False,
    "noise_variance": 0
}

# Device info (optional)
device_info = {
    "fingerprint": "web_browser_123",
    "location": "US",
    "pattern": "standard",
    "client_type": "web"
}

# Generate token
token = sycksec.generate(
    user_id="test_user_123",
    ttl=3600,  # 1 hour
    device_info=device_info,
    custom_recipe=custom_recipe
)

print("Generated Token:", token)
```

---

## ✅ Verify a Token

```python
# Verify token with custom recipe
payload = sycksec.verify(
    token=token,
    user_id="test_user_123",
    custom_recipe=custom_recipe
)

print("Verified Payload:", payload)
```

---

## ♻ Refresh Token if Needed

```python
# Simulate near-expiry in test mode
os.environ['SYCKSEC_ENV'] = 'test'  # For demo; remove in production

refreshed_token = sycksec.refresh_token_if_needed(
    token=token,
    user_id="test_user_123"
)

if refreshed_token:
    print("Refreshed Token:", refreshed_token)
else:
    print("Token still valid, no refresh needed")
```

---

## 📡 API Usage

* **`generate(user_id, context, custom_recipe)`** — Create a new token bound to the provided context.
* **`verify(token, user_id, custom_recipe)`** — Verify, decrypt, and check context validity.
* **`refresh_token_if_needed(token, user_id)`** — Refresh before expiry while keeping context.

---

## ⚠ Security Considerations

* Always transmit SyckSec tokens over HTTPS.
* Use `HttpOnly` + `Secure` cookies for web delivery.
* Enable context binding for sensitive applications.
* Rotate keys regularly in SaaS mode.
* Review audit logs for anomalies.
