LabGrown

LabGrown is a collection of hand-crafted, reusable modules that are built from scratch to replace heavy or restrictive third-party libraries.
This repo is where I experiment, refine, and maintain lightweight alternatives for common project needs.

Repository Structure

LabGrown/
└── Auth/
  └── JWT.py   # Custom implementation of JWT

• Auth/JWT.py – A simplified and reusable implementation of JSON Web Tokens (JWT).
  Designed for projects where full-blown libraries are overkill, or where more control and customizability are required.

---

JWT Module

Features

• Encode and decode JWTs without external dependencies.
• Support for customizable headers, payloads, and signing algorithms.
• Built with simplicity and clarity in mind for learning and extension.
• Drop-in ready for new projects – just import and use.

Example Usage

from Auth.JWT import JWT
import time

# Initialize with a secret key
jwt = JWT(secretKey="super-secret-key")

# --- Create a token ---
token, ttl = jwt.createJWT(
    payloadPartials={"user_id": 123, "role": "admin"},
    age=5  # token valid for 5 seconds
)

print("Generated Token:", token)
print("Token TTL (seconds):", ttl)

# --- Verify the token immediately ---
is_valid, data = jwt.verifyJWT(token)
print("Immediate Verification:", is_valid, data)

# --- Wait for token to expire ---
time.sleep(6)

# --- Verify again after expiration ---
is_valid, data = jwt.verifyJWT(token)
print("Post-Expiration Verification:", is_valid, data)

Vision

LabGrown is intended to grow into a toolkit of DIY modules for:

• Authentication systems (JWT, SWT, custom token formats).
• Application primitives (plans, configs, utilities).
• Other building blocks I rewrite for clarity, learning, and reusability.

Every component here follows the same philosophy:

• Simplicity over complexity
• Control over black boxes
• Reusability across projects

---

Future Plans

• Add SWT.py (Simple Web Tokens).
