## Content
```tsx
import { secureHeaders, NONCE } from 'hono/secure-headers'
import type { SecureHeadersVariables } from 'hono/secure-headers'
// Specify the variable types to infer the `c.get('secureHeadersNonce')`:
type Variables = SecureHeadersVariables
const app = new Hono<{ Variables: Variables }>()
// Set the pre-defined nonce value to `scriptSrc`:
app.get(
'*',
secureHeaders({
contentSecurityPolicy: {
scriptSrc: [NONCE, 'https://allowed1.example.com'],
},
})
)
// Get the value from `c.get('secureHeadersNonce')`:
app.get('/', (c) => {

<html>
<body>
{/** contents */}
<script
