On this page you can download the freeware ATOMIX virtual cipher machine.

The ATOMIX cipher machine is an advanced virtual Cold War era electro-mechanical rotor machine, situated between the Enigma and the Fialka M-125 cipher machines.

With its eight irregular stepping rotors, moving in both directions, the ATOMIX has a far better cryptographic strength than the Enigma and a tremendous key space. Its flexible pin settings provide many more different rotor movements than the Fialka. This very realistic virtual ATOMIX enables you to encipher and decipher messages, and apply the key settings as you would with an actual machine. There's also a formatted clipboard and Autotyping function. The program comes with a very complete helpfile, containing the manual, the enciphering procedures and all technical details on the machine. On the bottom of this page you can find some screenshots, taken from the program.

Runs on Windows™ 98/ME/2000/XP/Vista/Win7 and with WINE on Linux or Parallels Desktop on MAC.
