Webhook Secret Generation

The webhook requires a strong secret to secure remote updates. Use one of these methods to generate a secure secret:

Option 1: Using Python

import secrets
print(secrets.token_hex(32))  # Generates a 64-character hex string

Option 2: Using OpenSSL

openssl rand -hex 32

Option 3: Using /dev/urandom (Linux/Mac)

head -c 32 /dev/urandom | xxd -p -c 32

Add the generated secret to your .env file:
