EscapeHtmlInput

EscapeHtmlInput is a technique used in web development to prevent Cross-Site Scripting (XSS) attacks by converting potentially harmful characters in user input into a safe format. This process involves replacing special characters with their corresponding HTML entities, which are interpreted as text rather than executable code by web browsers.

The primary goal of EscapeHtmlInput is to ensure that user-generated content is displayed as plain text rather than executable HTML or JavaScript. This is crucial for maintaining the security and integrity of web applications, as it prevents attackers from injecting malicious scripts that can steal sensitive information, manipulate the user interface, or perform other harmful actions.

Common characters that are escaped include angle brackets (< and >), which are used to define HTML tags, and ampersands (&), which are used to denote HTML entities. For example, the less-than symbol (<) is replaced with &lt;, the greater-than symbol (>) is replaced with &gt;, and the ampersand (&) is replaced with &amp;.

EscapeHtmlInput is typically implemented on the server side, where user input is processed before being stored in a database or displayed on a web page. It can also be applied on the client side using JavaScript libraries or frameworks that provide built-in functions for escaping HTML input.

In summary, EscapeHtmlInput is a vital security measure in web development that helps protect against XSS attacks by converting potentially harmful characters in user input into a safe format. By ensuring that user-generated content is displayed as plain text, EscapeHtmlInput helps maintain the security and integrity of web applications.
