Secure HTML - a free online service that creates password protected Web pages.

Secure HTML - online service


If you have some information that should be kept confidential, but still easily accessed from your browser (for example, logins and passwords), this free online service can solve the problem.

It takes any HTML code and creates new "secure" HTML file that is encrypted and asks for a password when you try to open it. If you enter the correct password, you'll see the original document, otherwise you'll see the blank window or a few meaningless characters.

This method of creating password protected web pages is safer than many others, since the browser caches the encrypted version of the file and the original version exists only on your screen.

Copy the source code of any HTML page and paste it into the box or just type in whatever you want to encrypt, either HTML or plain text.
(Most browsers will view the source code of a Web page by right clicking your mouse, and choosing something similar to "view source" from the menu.)

Additionally, if you're using Internet Explorer, you can switch from Plain text/HTML to Rich text and use an easy WYSIWYG MS Word-like editor. You can edit your text in either mode, switching back and forth when you like.

Then enter Password (not less than 4 characters) and press the Encode button. Your browser will open a new window and ask you for a password. Enter it correctly and you'll see the original document. To save the encrypted file on your hard disk, choose File > Save As... from the browser menu and name the file whatever you like.

This service can also restore the original file. Copy the source code of an encrypted HTML page, paste it into the box, enter the correct Password, press the Encode button, and you'll get the original page opened in a new window. You can save it using File > Save As... from the browser menu.

Note: by default, Internet Explorer disables JavaScript in local HTML files and the window.prompt JavaScript method.
So, if you are using IE, you need to check...

  • Tools > Internet Options > Advanced > Security > Allow active content to run in files on My Computer.
  • Tools > Internet Options > Security > Internet > Custom Level > Allow websites to prompt for information using scripted windows > Enable.
