HTML Executable comes with a lot of security options to protect the HTML source code of your compiled websites and to restrict user access and rights to your ebooks.

• First of all, HTML pages and graphic files are never extracted to the user's hard disk. When the ebook needs to display a page, it directly reads it from its compressed data into the memory. This does not apply to Self-Extracting ebooks, however.
   
• Ebooks compiled with HTML Executable cannot be decompiled back to the website source files, especially if you password protect them. End users also can't extract files from the ebook using common file archivers (Zip, 7-Zip, Rar, Cab...) because HTML Executable uses its own data compression scheme. Finally, it is not possible to view the contents of an ebook without running it.
  
• Flash SWF, Flash video FLV, media (MP4, MP3...) files, Acrobat PDF and other plug-in source files... can stay in memory and thus they are not unpacked to the hard disk thanks to virtualization, a feature provided by HTML Executable.

Global Security Options

• Lock your ebooks with passwords. Only allowed users can get access to your ebooks!
• In order to create a set of acceptable passwords that can be unique, when distributing to a set of customers, wild card characters are accepted for passwords: Allowed: # digit (0..9), _ character a..z and A..Z, * any character... So, you can set up the following global password: 123-4**-A** (and so any character can be input for the wildcard place holder).
• Add an expiration date.
• Ebooks can verify their integrity at startup to prevent external modifications or truncated downloads.
• Disable the PRINT SCREEN key and similar combinations.
• Avoid multiple instances of an ebook: only one instance of the ebook can be optionally run at a time.

Manage User Rights

In HTML Executable, you can assign security profiles to your HTML pages. These security profiles determine what actions end users may do when viewing the associated pages. With them you can

• prevent users from copying HTML contents to the clipboard.
• configure the pages to appear like static dialog boxes (static text).
• turn printing of pages on or off.
• allow or disallow pages to be indexed by the built-in search function ("searchable" page).
• disable the mouse context menu.

By default, ebooks do not have the "Show source source" menu command in their context menu, so end users cannot access the source code of your HTML pages.

Restrict access to pages

You can also lock the pages you want and define conditions to fulfill in order for the end user to unlock them (password to enter, etc...).

For instance, create demo or trial ebooks and have locked specific pages with a password, which forces end users to buy the ebook in order to access the remaining pages.

• Single or groups of pages may be locked differently.
• You can create your own conditions using scripting.
• Do not allow end users to copy text from locked pages.
• Display custom error messages when a locked page is requested. For example, show a link to your order page...
