TrustedHTML

Limited availability.

This feature is not Baseline because it does not work in some of the most widely-used browsers.

• See full compatibility
• Report feedback

Note: This feature is available in Web Workers .

The TrustedHTML interface of the Trusted Types API represents a string that a developer can insert into an injection sink that will render it as HTML. These objects are created via TrustedTypePolicy.createHTML() and therefore have no constructor.

The value of a TrustedHTML object is set when the object is created and cannot be changed by JavaScript as there is no setter exposed.

Instance methods

Returns a JSON representation of the stored data.

A string containing the sanitized HTML.

In the below example we create a policy that will create TrustedHTML objects using TrustedTypePolicyFactory.createPolicy() . We can then use TrustedTypePolicy.createHTML() to create a sanitized HTML string to be inserted into the document.

The sanitized value can then be used with Element.innerHTML to ensure that no new HTML elements can be injected.

Specifications

Browser compatibility.

BCD tables only load in the browser with JavaScript enabled. Enable JavaScript to view data.

Cracking the Shell of Mystery

This document requires ‘trustedHTML’ assignment: what does it mean and how to fix it?

Have you ever been asked to “trust” a document before opening it? If so, you’ve likely encountered a document that has been assigned a “trusted HTML” label. This label indicates that the document has been scanned for malicious content and has been deemed safe to open.

But what exactly is “trusted HTML”? And how can you be sure that a document with this label is actually safe?

In this article, we’ll take a closer look at trusted HTML and explain how it can help you protect yourself from malicious documents. We’ll also provide some tips for identifying and avoiding documents that have been falsely labeled as trusted.

What is trusted HTML?

Trusted HTML is a security feature that is used to protect users from malicious documents. When a document is assigned a trusted HTML label, it means that it has been scanned for malicious content and has been deemed safe to open.

The trusted HTML feature is based on a set of rules that are used to scan documents for malicious content. These rules are designed to identify documents that contain viruses, worms, Trojan horses, and other types of malicious code.

If a document does not pass the trusted HTML scan, it will not be assigned a trusted HTML label and will not be able to be opened. This helps to protect users from accidentally opening malicious documents and exposing their computers to infection.

How can you be sure that a document with a trusted HTML label is safe?

While the trusted HTML feature is a valuable security tool, it is important to remember that it is not foolproof. There is always the possibility that a malicious document could be falsely labeled as trusted.

That’s why it is important to exercise caution when opening any document, even if it has a trusted HTML label. Here are a few tips for identifying and avoiding documents that have been falsely labeled as trusted:

• Only open documents from trusted sources. This is the most important tip for avoiding malicious documents. If you don’t know the source of a document, don’t open it.
• Scan documents with a virus scanner before opening them. Even if a document has been assigned a trusted HTML label, it is still a good idea to scan it with a virus scanner before opening it. This will help to protect you from any malicious content that may have been missed by the trusted HTML scan.
• Be suspicious of documents that ask you to enable macros or JavaScript. Malicious documents often contain macros or JavaScript that can be used to install malware on your computer. If a document asks you to enable macros or JavaScript, be very careful and only do so if you are sure that the document is from a trusted source.

By following these tips, you can help to protect yourself from malicious documents and keep your computer safe.

What is TrustedHTML?

TrustedHTML is a security feature that is used to prevent malicious code from being executed in a web browser. It works by verifying that the HTML code that is being loaded has been signed by a trusted publisher. This prevents attackers from injecting malicious code into a website and tricking users into running it.

TrustedHTML is implemented by the browser, and it works by checking the digital signature of the HTML code that is being loaded. The signature is a unique identifier that is generated when the HTML code is created. The browser checks the signature against a list of trusted publishers, and if the signature is valid, the HTML code is loaded. If the signature is not valid, the browser will block the HTML code from being loaded.

TrustedHTML is a very effective security feature, but it can also be a burden for developers. This is because developers need to create signed HTML code in order for it to be loaded in a browser. This can be a time-consuming process, and it can also be difficult to get right.

Despite the challenges, TrustedHTML is an important security feature. It helps to protect users from malicious code, and it is a valuable tool for developers who want to create secure websites.

Why is TrustedHTML required?

TrustedHTML is required for a number of reasons. First, it helps to protect users from malicious code. Malicious code can be used to steal personal information, install malware, or even take control of a user’s computer. TrustedHTML helps to prevent this by blocking malicious code from being executed in a web browser.

Second, TrustedHTML helps to protect websites from being compromised. If a website is compromised, an attacker could inject malicious code into the website and trick users into running it. TrustedHTML helps to prevent this by blocking malicious code from being loaded in a browser.

Third, TrustedHTML helps to protect businesses from data breaches. Data breaches can be very costly for businesses, and they can damage their reputation. TrustedHTML helps to prevent data breaches by blocking malicious code from being executed on a computer.

Overall, TrustedHTML is a very important security feature. It helps to protect users, websites, and businesses from malicious code. It is a valuable tool for developers who want to create secure websites.

How to implement TrustedHTML?

TrustedHTML is a security feature that allows you to specify which HTML tags and attributes are allowed on your website. This can help to prevent cross-site scripting (XSS) attacks, which are a type of attack that can be used to steal user credentials or inject malicious code into a website.

To implement TrustedHTML, you need to add the following code to your website’s header:

This code will tell the browser to only allow HTML tags and attributes that are listed in the `trusted-types.min.js` file. You can find a list of the allowed tags and attributes in the [Trusted Types documentation](https://trustedtypes.org/docs/).

Once you have added the code to your website’s header, you need to make sure that all of your HTML tags and attributes are listed in the `trusted-types.min.js` file. If you have any tags or attributes that are not listed, the browser will not allow them to be rendered on your website.

You can add tags and attributes to the `trusted-types.min.js` file by following these steps:

1. Open the `trusted-types.min.js` file in a text editor. 2. Find the section of the file that lists the allowed tags and attributes. 3. Add your tags and attributes to the list. 4. Save the file.

Once you have added your tags and attributes to the `trusted-types.min.js` file, you need to recompile the file. You can do this by running the following command in the terminal:

npm run build

Once the file has been recompiled, you can deploy it to your website.

Common TrustedHTML errors

There are a few common errors that you can make when implementing TrustedHTML. These errors can prevent your website from working properly or they can make it vulnerable to XSS attacks.

1. Not including the `Content-Security-Policy` header

The `Content-Security-Policy` header is required for TrustedHTML to work. If you do not include this header, your website will not be protected from XSS attacks.

2. Not using the `trusted-types.min.js` file

The `trusted-types.min.js` file is required for TrustedHTML to work. If you do not use this file, your website will not be protected from XSS attacks.

3. Not including all of your tags and attributes in the `trusted-types.min.js` file

You need to make sure that all of your tags and attributes are listed in the `trusted-types.min.js` file. If you do not include all of your tags and attributes, the browser will not allow them to be rendered on your website.

4. Using invalid tags or attributes

You can only use tags and attributes that are listed in the `trusted-types.min.js` file. If you try to use a tag or attribute that is not listed, the browser will not allow it to be rendered on your website.

5. Using tags or attributes incorrectly

You need to make sure that you are using tags and attributes correctly. If you use them incorrectly, the browser may not be able to render them properly or it may be vulnerable to XSS attacks.

6. Not updating the `trusted-types.min.js` file

The `trusted-types.min.js` file is updated regularly with new tags and attributes. You need to make sure that you are using the latest version of the file. If you are not using the latest version, your website may not be protected from new XSS attacks.

TrustedHTML is a powerful security feature that can help to protect your website from XSS attacks. However, it is important to implement TrustedHTML correctly in order to avoid common errors. By following the steps in this document, you can help to ensure that your website is protected from XSS attacks.

This document requires 'TrustedHTML' assignment

Hello, I made this simple code, const newElement = document.createElement('div'); var innerHTMLText = 'Traduci'; 'use strict'; newElement.innerHTML = innerHTMLText; document.body.appendChild(newElement); but when I run it chrome give me this error This document requires 'TrustedHTML' assignment How can get ride of it and made my code working

its work for me, update ur browser.

The error you're encountering is related to a security feature in Chrome that requires TrustedHTML assignment for certain operations, such as assigning to innerHTML . This is part of Content Security Policy (CSP) and is designed to prevent Cross-Site Scripting (XSS) attacks¹.

Here are a couple of ways to address this issue:

Method 1: Using Trusted Types API You can create a policy using the Trusted Types API that returns the same input string. Here's how you can do it:

Then, you can use this policy in your code:

Method 2: Using DOMPurify Another approach is to use DOMPurify, a library that sanitizes HTML and prevents XSS attacks¹. Here's how you can use it:

First, install DOMPurify:

Then, use it in your code:

Please note that these methods are designed to maintain the security benefits of TrustedHTML assignment while allowing your code to function as intended¹². If your output doesn't require any markup, you could also consider changing from innerHTML to innerText ³.
