De Duitsers lieten echter na om deze sleutelgrootte in de praktijk toe te passen. Zij produceerden slecht 36 verschillende templates om de rijen te drukken. Bovendien waren berichten meestal nooit langer dan 60 letters waardoor het aantal gebruikte rijen beperkt was.

The variables above give a total key size of 2.06 x 10185. Unfortunately, the Germans failed to apply this key space on RS-44. They only produced 36 different rods to print the rows. Also, the actual messages were mostly never longer than 60 letters, limiting the numers of rows that were used. With all possible permutations for the transposition key and start positions there's only a practical key space of 2 x 1035, comparible with a 117 bit key. The conversion alphabet for place names is a simple substitution and, although it has 15,511,210,043,330,985,984,000,000 possible combinations, can be solved with simple letter frequency analysis. This, of course, is only possible if the rest of message is already broken successfully and the grid and column order is restored correctly.

De Crypto Box is een tool om tekst te vercijferen door het verplaatsen van letters. Dit gebeurt door het verschuiven van de rijen en kolommen van het lettervierkant. Ontcijfering van de tekst bewees een hele uitdaging te zijn door het grote aantal mogelijke combinaties en de complexe wijze waarop de letter rondschuiven.

The Crypto Box is a tool to encrypt text by moving the letters. This is done by shuffling the rows and columns of the text square. Retrieving the original position of the letters has proved to be a real challenge due to the large number of possible moves and the complex way the letters travel around the square. Even the simplest shuffles with a few steps create a true brain-teasing puzzle. More steps means a more complex encryption. There are 39 ways to move a row or columns in the box (moving a row back is useless so the 40th doesn't count). For five steps this already gives 40 * 39 * 39 * 39 * 39 = 92,537,640 possible combinations. Each further step multiplies the result with 39. With only 40 steps you will have 4.5x1063 combinations, comparable with an enormous 212 bit key!

Voor Legrand's bericht beginnen we met een geruit blad en schrijven het geheime bericht er op met pen. Laat enkele lege rijen tussen elke rij van het bericht, om je oplossing eronder te schrijven in potlood (eenvoudig te corrigeren met gom).

For Legrand’s message, start by taking a sheet with squares and write down the secret message with a pen. Leave some blank rows between each row of the message, to write your solution underneath the symbols with a pencil (easily corrected with a gum). Count how many times each of the symbols appears in the cryptogram and write down the results in a table, ordered from most to least frequent. You will see that one of the symbols clearly stands out. This is the first major clue. That most frequent symbol represents without doubt the most frequent letter of the alphabet. Write your first results underneath the according symbols on your message sheet.

The Cysquare has a grid with 676 (26 x 26) cells. Each row has 10 empty cells for the message text and 16 black cells. However, three rows contained 20 empty cells and three other rows contained only black cells. The daily key consisted of a randomly shuffled alphabet and the numbers from 1 to 26 written underneath them, also in random order. Both random alphabet and numbers are written from left to right at the top of the grid and from bottom to top on the left side of the grid.

Dit is echter een theoretisch getal. In werkelijkheid zijn er veel minder combinaties omdat het de codebreker niets uitmaakt hoe de kolommen en rijen benoemd worden of hoe de berichtsleutel werd gecodeerd.

This gives a overall theoretical total of 7,95 x 10280 different ways to construct a RS 44 key sheet, comparable with a 934 bit key. This, however, is a theoretical number. In reality, there are far less combinations, because a codebreaker won't not care about how the columns and rows are labelled, or how the message key is converted. He just needs to know how the letters are actually placed in the 600 cells and how they are taken from the columns. He takes in account the following properties:

The CT-37 table is an extended version of the straddling checkerboard and includes additional characters. The table is easy to remember. It uses the 7 most frequent English letters "ESTONIA" in the top row. The two following rows are the remaining letters, completed with the "FIG" field. The fourth row contains the "SPACE" and "CODE" field with the punctuation marks between them (less critical to remember).

The ciphertext is taken from the columns and immediately written in five-letter groups. For the sake of our example, we give the columns and corresponding letters. Notice the irregular length of the columns, caused by the fractioning of the rows.

Het originele checkerboard werkt met kolommen en rijen. Indien de letter in de eerste rij staat gebruikt men het cijfer er net boven. Indien de letter in de tweede of derde rij staat gebruikt men het cijfer van de rij en het cijfer in de kolom boven de letter ( R = 4, H = 85, P = 90 etc).

The original checkerboard works with columns and rows. If a letter is found in the first row, we take the digit of the column. If the letters is found in the second or third row we take the digit of that row and the digit of that column ( R = 4, H = 85, P = 90 etc).

Dit resulteert in een complexe transpositie van de letters. Eerst bepalen we het exacte aantal rijen en kolommen (vergeet niet aan te vullen met X'en om een laatste groep van vijf letters te bekomen).

The disrupted transposition is as a further complication to the normal transposition. Instead of filling the matrix row by row, the rows are all filled in a very irregular fashion, resulting in two separate areas. This results in a very complex transposition of the characters. First, we determine the exact number of rows and columns to fill (don't forget to complete with X's until we have a final group of five letters) Next we fill a row until we reach the digit from the keyword sequence. If the first digit is at the 8th place, we will only fill that row up to that position. We continue the next row until the second position and so on. If we have reached the end position of the last line we continue by filling the remaining empty places at each line. In our example the difference between the two areas is visible by the lower and upper case characters.
