Detailed Overview
The HTML Entity Encoder converts special characters into HTML entities, such as &, <, >, " and ', and decodes entities back into plain characters. Encoding is what stops user-supplied text from being interpreted as HTML when it is displayed on a page, which is a basic defence against cross-site scripting problems in content that comes from users.
To use it, paste the text, choose encode or decode, and copy the result. When you are inserting untrusted text into a page, encode it before it reaches the HTML, so characters like < and > display as text instead of starting a tag. When you receive encoded content from another system, decode it to read the original characters and confirm the content is what you expected.
Watch out for double encoding, where text that is already encoded gets encoded again and visitors see literal entity codes instead of the intended characters. If output looks like &amp; instead of &, the input was probably already encoded, so start from the plain version. Also check that the context matters: encoding for HTML body text is different from encoding for attributes or URLs.
One honest limitation: entity encoding is only one layer of protection. Proper defence against scripting attacks also depends on how your application handles attributes, scripts, URLs and other contexts, so encoding alone is not a complete security solution and should sit alongside your framework's normal escaping.
