Why Escape HTML?
HTML escaping is the process of converting special characters (like <, >, &, ", ') into their corresponding HTML entities (<, >, &, ", '). This is a critical security practice for web applications.
Key Use Cases:
- Preventing Cross-Site Scripting (XSS): If you display user-generated content on a webpage, escaping it prevents malicious users from injecting scripts (e.g.,
<script>alert('hacked')</script>) that could run in other users' browsers. - Displaying Code Snippets: To show HTML code as text on a webpage, you must escape it. Otherwise, the browser will try to render the code as actual HTML elements.
Unescaping is the reverse process, converting HTML entities back into their original characters. This is useful when you receive escaped data and need to process the original content.
