  2. Right click on the selected files or folders and select Encrypt under the popup menu item xTyFileCrypter. For the first time you encrypt files, you will be asked to enter an encryption key (another way to say password) with a key name. The key name is not used in encryption, but if you cannot decrypt a file later because you forget which key you used, the key name might give you a hint.

    If you want to use this same key to encrypt files in the future, check the Remember and always use this key to encrypt. If you don't check this box, the key you entered will be automatically erased when you log off or restart the computer.

    WARNING: You must remember your encryption key. If you forget the key, you will never be able to decrypt the files that you have encrypted.

    Click OK to continue.

  3. On the next window, first verify if the key is the one that you want to use. If not, click the Change Key button to enter a different one.

    • If you want to encrypt each file individually, click the Encrypt button to start encrypting.

How to encrypt HTML pages?
HTML web pages can be encrypted using xTyFileCrypter. Once they are encrypted, you can publish them on web servers safely. Only those having the key will be able to view the content with the free Internet Explorer extension xTyHTMLDecrypter (download xTyFileCrypter). Nobody (even those with the key) will be able to view the HTML code. This is a secure and effective way to protect your HTML code or sensitive web data. Typical samples are this one and this one. You will be able to view the former with the key color, but you will never be able to view the latter.

To encrypt HTML files, (1) save a copy of the original HTML documents. (2) Follow the same steps above for encrypting files and don't forget to check the Encrypt HTML files checkbox on the popup Confirm... window.

Only valid HTML documents that you selected will be encrypted. All other files such as images will NOT be encrypted. To be specific, it will only encrypt files containing the valid HTML tags body and the /body tags. All the text between these two tags will be encrypted.

HTML pages that contain server-side script such as ASP or PHP code should NOT be encrypted using xTyFileCrypter. Instead, you should use the server component xTyAESCrypter to dynamically encrypt the part of the page that need to be protected. This is a sample of this type.

NOTE: xTyFileCrypter does not decrypt the encrypted HTML documents. They can only be viewed by Internet Explorer with xTyHTMLDecrypter xTyFileCrypter is freely available and it can be downloaded at here. So you need to save the original HTML document.

Why should I encrypt HTML pages?
Encrypted web pages can be used to protect your page source code and resources that are linked to the page, such as images and other documents.

More importantly, if you have information that you want to share with your co-workers or business partners, you can encrypt the pages and publish them on your web server. In this way, your co-workers or partners can easily access the information with Internet Explorers, and nobody else will be able to view the encrypted contents.

As an example, this is a full list of my passwords and other related information that I need from time to time to log on to my online accounts. First I save the list as an HTML web page, and then I encrypt it and put it on my web server. In this way, I don't have to remember any of the user IDs or passwords. Whenever or wherever I need them, all I need to do is navigate to this page and type in the key. Nobody else including you will be able to see my passwords.

Some other samples can be found here.

How to shred files and folders?
  1. Open a Windows Explorer window and select the files or folders that you want to shred.

    Remember? By holding down the SHIFT key or CTRL key while you click, you can select multiple files or folders.

  2. Right click on the selected files or folders and select Shred under the popup menu item xTyFileCrypter.

    WARNING: Shreded files cannot be recovered.
