HTML encoding converts characters that are not allowed in HTML into character-entity equivalents; HTML decoding reverses the encoding. For example, when embedded in a block of text, the characters < and > are encoded as < and > for HTTP transmission.
HTML Encoding refers to the process of converting certain characters in plain text into a format that can be securely displayed as HTML content. HTML encoding is essential to prevent security vulnerabilities, as well as to ensure the proper display of special characters, such as angle brackets, ampersands, and quotes, which have a specific meaning in HTML.
When a user inputs text into a web page, it is important to encode it to prevent potential security vulnerabilities, such as cross-site scripting (XSS) attacks. This can be done using HTML entity encoding, which replaces special characters with their equivalent HTML entities, such as "&" for "&".
HTML encoding can also be used to display characters that are not typically found in standard keyboard input, such as special symbols, mathematical operators, and other characters from different alphabets. For example, the HTML entity for the euro symbol is "€".
In order to perform HTML encoding, one can use various programming languages such as JavaScript, PHP, and others. However, it is important to ensure that encoding is performed consistently and correctly, as even a single missing encoding can lead to a security vulnerability.
In conclusion, HTML encoding is an essential process for ensuring the security and proper display of HTML content. By converting special characters into their equivalent HTML entities, web developers can prevent potential security vulnerabilities and ensure that characters are displayed correctly on web pages.
Summary: HTML Encoding is the process of converting certain characters in plain text into a format that can be safely displayed as HTML content. It helps prevent security vulnerabilities, such as cross-site scripting (XSS) attacks, and ensures that special characters are displayed correctly. HTML encoding can be performed using programming languages like JavaScript, PHP, etc. It is crucial to perform encoding consistently and correctly to prevent security vulnerabilities.
