Vigenère Cipher Visualization Tools Download Page

This page has three versions of our Vigenère Cipher Visualization prototype software for Windows, Linux and MacOS.

Installation

Click here to download the Windows version.
This version is a self-extracting one with name VIGvisualWin.exe.

Download this file to a selected directory and run it by double-clicking on its icon.
This program will run, create a directory VIGvisualWin, and save all files to this directory.
Double-click the program VIGvisual.exe to run it.

Click here to download the Linux version. This version is a standard Unix tar.gz files with filename VIGvisualLinux64.tar.gz

Download this file to a selected directory.
The standard Unix way to uncompress and untar this file is to run the following commands

gzip -d *.gz; tar xvf *.tar

A binary executable VIGvisual will be created in the directory VIGvisualLinux64. This is the Vigenere Cipher Visualization program.

Click here to download the MacOS version.
This version is a standard zip file with name VIGvisualMac.zip. However, the MacOS version requires some extra work to be installed properly.

Download this file to a selected directory.
If you are using an Unix based machine, run the following command

unzip *.zip

This will create several directories. The Vigenere Cipher Visualization software is in VIGvisualMac/VIGvisual.app/Contents/MacOS/VIGvisual
If you are using a MacIntosh machine, doulbe click the zip file and this will create a directory VIGvisualMac, which contains executable VIGvisual.
However, you need one more step because the Qt library is not provided. The package can be downloaded from the following link (recommended): http://download.qt-project.org/archive/qt/4.8/4.8.4/qt-mac-opensource-4.8.4.dmg.
