Objectives
The Microsoft company in its Microsoft Internet Explorer browser of version 5.0
and higher supplies functionality of coding (encrypting) some fragments of
content of HTML page. For instance, it may be a Java Script scenario executed
on the Client side. In this connection, non-readable, encrypted code is
displayed to a user when he chooses to browse the source of such an HTML
document.
|
|
The Customer offered us to solve the task of decrypting such documents and
implement a tool which allows to browse text encrypted by means of IE browser
functions. This tool was intended for development control and the debugging of
web-oriented system developed and supported by our Customer. The components of
the system generated encoded content of HTML pages which was necessary to
control and debug.
|
| |
|
Results
As a result of the project we implemented the algorithm of decrypting such HTML
documents as well as DLL library (COM component) supplying corresponding
functions
|
|
to a user. The installation of this component under Windows OS enables a user
to browse the content of HTML pages encrypted with the mentioned method.

Technical peculiarities
As a technical peculiarity of this project we would like to mention
non-standard and complicated algorithm of HTML page decrypting as well as the
program format itself. This tool was implemented as the DLL library - Add-In
component for Windows OS, which was bound to HTML file type. The functionality
of this component extends Windows context menu, which is displayed to a user
when he chooses an HTML file in system and clicks the mouse right button on its
icon. Thus, it is possible just
|
|
to chose an HTML file with encrypted fragments, click the mouse right button on
it, choose "Decode HTML Source" option and get the copy of this HTML page with
the readable (decrypted) content, stored on a hard disk. We deliberately do not
publish technical details of the project implementation, as they constitute the
private property of our Customer. However, if you are interested in some
technical aspects of the project you may address your questions to
