- This is an encryption machine that will allow you to encrypt your own messages and in addition we have provided 8 secret messages for you to try and solve.
Send and receive secret messages to anyone who has a machine. its quite easy to use but creates messages that can be extremely complex to decode.
Hardwood construction with gears cut from ¼” thick wood. All letters and text are deeply laser engraved into the wood. The gears turn on alloy steel pins. Made in USA and designed to last a lifetime.
Available in 2 different sizes. The larger one measures approx. 12.75” x 4.5” x 1”. Each gear is approx. 3.75” in diameter . The smaller size measures 9.4” x3.2” x 1”. Each gear is approx. 3.75” in diameter)

We have also recently done the Confederate Army Cipher, the Union Army Cipher (used for flag signaling) and th Mexican Army Cipher

Interesting,but if I understand this right the 3 wheels have all 26 letters on 26 cogs.So this means that they are all moving synchroniicly.
So if I am not mistaken this means the machine at the end works like a monoalphabetic substituion cypher like the Ceasar cypher.
To explain it differently:if you for example want to code ABBA the A will allways be coded to the same letter.So like I wrote a simple monoalphabetic substitution.So because the 3 wheels move synchronically it does also not matter how manny wheels you use for your machine.The result will be the same with even 100 wheels.
The problem with a monoalphabetic substitution is,that it is eaily broken by frequency analysis.
The principle of the enigma(only looking at the rotors now)is different:The three rotors of the ENIGMA do all a monoalphabetic substitution,BUT they turn asynchronically.So even the "kickoff point ,the point where the next wheel in the row also makes a turn is ajustable here.
So in your example to make a simple coding machine in this form I would suggest the simplest way ist to use different wheels(gears),different sizes.
This would have the result that if wheel a makes a full turn wheel b makes(suposed u use a smaller gear) f.e 2,5 turns.
So in this case if you code AAA f.e.,ewvery A will be codet to a different letter.
Still to be honest,the code would be much easier broken like the ENIGMA code(not going into detail here).
But it will make a big change for everyone trying to break your coded message then.
It would probably be a form of Vinegere code in this case,but unfortunately Vinegere ist already broken.
Volker Schmidt Thanks for your input. As there are 2 cipher gears working together, worst case its not really monoalphabetical, more like dual. But the complexity arises because both the wheel orders and the wheel keys (orientation of each wheel after placed) can be changed as often as you want.
This is not to say that modern computer programs couldn't solve this; of course they could. But, the level of security is quite strong for normal purposes and not likely to be broken easily by non computer methods assuming reasonably frequent changes in keys.
As evidence to this ,my Enigma IV machine and Enigma V machine have $100 and $150 challenges if anyone can decode a supplied message. Any means is allowed including computers. It has been 6 months. We have had one solution on Enigma IV and one solution on enigma V. After these we solved a new more difficult challenge was posted and are still unsolved today.
I like your suggestions though and will look into them in more detail.
best,

the use of a keyword is critical on all ciphers. It no longer becomes monoaplhabetic. Watch the video to learn of this technique. Simple yet very powerful
very cool! Nice work!
I laughed extremely hard when you messed up the first letter as well ahaha!
Brilliant.
