The Secret to DOM Security

Many developers try to hide content by using display: none or blurring text with CSS. However, savvy users can simply right-click, choose "Inspect Element," and read the raw HTML in the developer tools.

To truly protect content without a backend server, you need to ensure the sensitive HTML does not exist in the document until the user is authorized...

Users will need this password to decrypt the content

Encrypted Output

Copy this for your implementation

Paste this string into your JavaScript code as the encrypted payload.

Implementation Code

Add this to your website

<!-- 1. Include CryptoJS -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/4.1.1/crypto-js.min.js"></script>

<!-- 2. Your encrypted content container -->
<div id="premium-content"></div>
<div id="password-form">
  <input type="password" id="password-input" placeholder="Enter password">
  <button onclick="unlock()">Unlock</button>
</div>

<script>
// 3. Paste your encrypted string here
const encryptedPayload = "YOUR_ENCRYPTED_STRING_HERE";

function unlock() {
  const password = document.getElementById('password-input').value;
  try {
    const bytes = CryptoJS.AES.decrypt(encryptedPayload, password);
    const decrypted = bytes.toString(CryptoJS.enc.Utf8);
    if (decrypted) {
      document.getElementById('premium-content').innerHTML = decrypted;
      document.getElementById('password-form').style.display = 'none';
    } else {
      alert('Incorrect password');
    }
  } catch (e) {
    alert('Incorrect password');
  }
}
</script>
How This Paywall Works

This tool creates client-side encrypted content using AES-256 encryption via the CryptoJS library. The key insight is that your protected HTML never exists in the browser until the correct password is entered.

Why CSS Hiding Doesn't Work

  • display: none - Content is still in the DOM, visible via Inspect Element
  • CSS blur/opacity - Same problem, the actual text is readable in source
  • JavaScript show/hide - Content loads in memory, can be accessed

Why Encryption Works

  • The HTML is converted to an encrypted string before being added to your page
  • Without the password, it's just random characters
  • The browser has no way to decrypt it without user input
  • Even viewing source or using dev tools shows only encrypted text

Security Considerations

  • Not for high-security needs: This is "low-friction" security, not bank-vault security
  • Password distribution: You still need a way to give users the password (email, purchase confirmation, etc.)
  • One-time unlock: Once decrypted, the content is visible until page refresh
  • No server required: Perfect for static sites, JAMstack, or simple implementations

Best Use Cases

  • Gated content for newsletter subscribers
  • Exclusive content for paying customers
  • Time-limited access codes for promotions
  • Simple member-only sections
  • Protecting solutions in educational content
