📦 Architecture Overview

1. Create OTP & Store Data

• User enters text (or uploads file/media)

• Server generates OTP

• Stores in Redis as:

otp:123456 → actual_text_or_file_url
TTL: e.g., 2 minutes

2. Share OTP

• User sends OTP to anyone.

3. Retrieve Data

• Receiver enters OTP

• Backend fetches Redis value

• Data auto-expires after TTL.

⚙️ Rate Limiting (express-rate-limit)

The backend uses express-rate-limit to block:

• Too many OTP generation requests

• Spam submissions

• Abuse from the same IP
