You need to change the extension of the file. The icon of a file is mapped to its extension. If you're using 95/NT, the easiest way is to add an extension, like "readme.txt" -> "readme.txt.cry", and then set your desired icon for files with the cry extension. That way you'll just have to remove the .cry when decrypting it, and the original icon is back.

I assume that you know how to create registry keys. Just att your extension to the HKEY_CLASSES_ROOT key with a default valu of your application name. Then add your application name as a key also under the HKEY_CLASSES_ROOT key and make a subkey named DefaultIcon containing the name of the file that contains the icon and the index of the icon.

You can look at for example the ".txt" extension that is already there.
