You can download Windows™ software simulations of cipher machines and crypto tools on the appropriate web pages or from my Dropbox. All software is written by myself and available as freeware for personal use and educational purposes. No trial versions, no shareware and no registration, only really free software! I don't have any commercial goals and do not advertise anything. I only advertise cryptology and its fascinating history.

Please download my software only from my official website or my Dropbox and carefully read the Readme.txt file and installation instructions. Bear in mind that the most recent versions are only available through my website! Because the source code to some of the software is published on the Internet you might encounter malicious clones elsewhere.

This site does not contain any spyware, adware or malware and it is checked on a regular basis with anti-virus software to keep it free from harmful software. Nonetheless, I encourage all visitors to check all downloads on this website and on other websites with anti-virus software. Prudence is a good habit!

Mirror Website

I created a mirror website that can be accessed in (the rare) case of problems with the original website. The mirror is not always up-to-date and only intended as a back-up. If you download from the mirror, the download is automatically redirected to the main website users.telenet.be. Also, the web mail and guestbook on the mirror do not work.
