What are HTML Entities?
In HTML, certain characters are reserved. For example, you cannot use the less than (<) or greater than (>) signs in your text because the browser might mix them up with tags. To display these reserved characters safely, developers must use character entities. For instance, the less than sign is written as <.
Why Use an HTML Entity Encoder?
- Prevent XSS Attacks: Encoding user input is a fundamental security practice. By converting special characters into entities, you prevent malicious users from injecting executable scripts (Cross-Site Scripting) into your web pages.
- Display Code Snippets: If you are running a programming blog or a documentation site, you need to show HTML code to your readers. If you don't encode the tags, the browser will render them instead of displaying the raw code.
- Ensure Valid HTML: Using entities ensures that your website's source code remains perfectly valid and doesn't break the layout or structure of the DOM.
