JWT Authentication API Documentation

JWT (Json Web Token) is a critical component for secure API access control. Below are key guidelines for implementation:

🔐 Core Concepts

• Token Structure: Header (algorithm/encryption), Payload (claims), Signature (security)
• Authentication Flow:
  1. Client sends credentials to auth endpoint
  2. Server generates JWT upon successful validation
  3. Client stores token in localStorage or HTTP headers
  4. Subsequent requests include Authorization: Bearer <token>

🛠️ Implementation Steps

1. Generate Secret Key
   JWT_Secret_Key should be 256-bit and stored securely

   

2. Configure Middleware

   # Example for Flask
   @app.route('/protected')
   @jwt_required()
   def protected():
       return jsonify(current_user)
   

3. Token Validation
   Always verify token expiration with exp claim

   

⚠️ Security Best Practices

• Use HTTPS for all communication
• Rotate secret keys periodically
• Implement token revocation mechanism
