About HTML Encoding:

• HTML encoding converts special characters to entities that can be safely displayed in HTML
• Essential for preventing XSS (Cross-Site Scripting) attacks when displaying user-generated content
• Three encoding types:
  • HTML Entities: &name; format (e.g., &lt; for <)
  • Hexadecimal Entities: &#xHH; format (e.g., &#x3C; for <)
  • Decimal Entities: &#DDD; format (e.g., &#60; for <)
• Common encoded characters:
  • < becomes &lt; or &#60; or &#x3C;
  • > becomes &gt; or &#62; or &#x3E;
  • & becomes &amp; or &#38; or &#x26;
  • " becomes &quot; or &#34; or &#x22;
• Always encode user input before displaying it in HTML to prevent injection attacks
