Frequently Asked Questions (FAQ)


Questions and Answers about HTML Guard

Which browsers does HTML Guard work with?

Pages that have been protected by HTML Guard can still be viewed in any current browser that supports JavaScript, such as Internet Explorer, Firefox, Opera, Google Chrome, Apple Safari or Konqueror.

This does not mean that all of HTML Guard's protective functions are available in all of these browsers. For example, Opera does not allow blocking access to the context menu with the right mouse button, or deactivating the selection of text. HTML Guard can only restrict a browser function if the browser allows this to be done.

What effect does the use of HTML Guard have on search engine rankings of websites?

HTML code that has been encrypted by HTML Guard cannot be read or interpreted by search engines. In contrast to today's browsers, the spiders used by search engines do not recognize JavaScript and can therefore not execute the source code used for encryption.

The encrypted content is therefore completely hidden from search engines, and this can have a negative effect on a page's search engine-friendliness. You should therefore only use HTML Guard's encryption function after due consideration, and apply it only to selected pages and portions of pages.

The remaining protective measures used by HTML Guard have no negative effect on your site's search engine ranking - they only add code or delete unnecessary pieces of code without having any effect on its basic structure.

How safe is the protection provided by HTML Guard?

It is impossible to achieve 100% protection of websites, and HTML Guard can therefore not claim to provide it. As long as content appears on your screen, there will always be a way to copy it. But with HTML Guard, you have a tool that can impede and restrict copying as much as it is possible to do so.

What are the differences between the demo and full versions?

The free evaluation version of HTML Guard adds an identifying notice to your pages. This notice disappears as soon as you unlock the full version.

Can HTML Guard also protect PHP, ASP, JSP or SHTML files?

Even HTML files with server-side scripting can be processed by HTML Guard, because encryption is applied solely to the client-side portion of the code. Scripts that are executed on the server are not touched, so that the server can continue to interpret them in the same way.

Can HTML Guard also encrypt JavaScript code?

JavaScript code embedded within HTML pages can be encrypted by HTML Guard without any problem.

Does this software support Unicode?

HTML Guard can process pages without regard to which character set is being used. For example, the software supports character sets such as UTF-8 (Unicode), KOI8-R (Russian), BIG5 (traditional Chinese characters) and Shift-JIS (Japanese).

Can the full version of HTML Guard be installed on more than one PC?

As long as only you alone are using the software, you can install and use the full version on different PCs. However, should HTML Guard be used in a commercial setting by several users, then each user must obtain a separate license.
