Gee, I had downloaded this one a long time ago and never installed it How silly of me! It sure does make things much easier.

This one, i did only by hand with no mistakes.

What I find hard with this, is that you have no way of checking if you're doing it right untill the very end. Usually, if i want to decrypt something, i'll give it a try on the first line or first few words to see if a clear message comes out and then I proceed with the rest. With this method it is impossible to do so. And it is not like if you make a small mistake only a few letters won't decrypt right, the whole thing is "11418 17113 2" up.
That was pretty fun to do

To decipher an Enigma and not to divide into groups => Straddling Checkerboard with Double Columnar (INDEPENDEN, LEONARDO, DAVINCI) => CT-46-OTP

Let's call this "Inception Cypher", a code within a code within a code...but still got it.
The fun thing about OTP is that with the same crypted text, given a different key, you will get different readable clear text. (see below)
Ciphertext: Q J K E S Q J K E S Q J K E S OTP-Key: X V H E U F J R A B D F P A B --------- --------- --------- Plain text: T O D A Y L A T E R N E V E R
this makes brute force attacks useless.

You have read my message? I wished to tell that we use strongly simplified variant of enciphering an Enigma. The choice of options for each day was more difficult, code reductions and Bigram table were applied. Very often messages were preliminary ciphered by the so-called officer code number. I suggest to unite OTP and Enigma. It will be cheerful.

Yes, I could read your message. I have read about the TRITON procedure somewhere in this forum and it seems like making things harder just for the hell of it but I will definitely give it a try someday. These new procedures and the various improvements of the machine (Enigma Uhr) make me feel like the germans knew there was something wrong with their Enigma's and they tried to patch it up with increasingly difficult ways of doing things. It makes me feel like a programmer that would patch bugs as they happen instead of taking time to re-write a bugless code.

Well Arnaud,
My hat off to you, impressive. After the first step (decoded the message with enigma) I can get any results with the checkerboard. Still trying. But again Arnaud kudos to you.

Well Arnaud, My hat off to you, impressive. After the first step (decoded the message with enigma) I can get any results with the checkerboard. Still trying. But again Arnaud kudos to you. The result you get from the enigma must not be in groups of 5 (there is a setting for that in the "clipboard tool" that you get when you click on the paper ribbon) Then you need to encode these letters in the checkerboard (I kept trying do decode them...habits are hard to quit) so that you get numbers which are then used as OTP key

Aha. I've done the first part correctly. But tried en decode. Thanks for clearing that. Indeed old habits...........

So the longer the key the safer the chiper?

Post by betacam on Jul 8, 2016 11:27:18 GMT
You have read the message? The length of a key should be equal in an ideal case with length of the message. It is impossible to use the long reasonable text as a key. It is possible to use only casual letters. A riddle of a disk 9 for me very difficult.

A riddle of a disk 9 for me very difficult. This part of your message I don't undrstand. Probably due to Google translation.
By the way, what is your mother tongue? Mine is french, and I also speak a bit of dutch but not as well as english.
