The first cipher was made by Julius Caesar who used it to communicate with his generals.
It is named 'Caesar Box' after the creater.
The system goes as follows:
First selct a message to be encrypted. Make sure the length of the characters your message is a perfect square.
For example: "CAESAR BOX"
Write it in a square grid (here, 3*3 grid)
C A E
S A R
B O X
Now read it horizontally....
The encrypted message shall be CSBAAOERX Ensei's background, although correct, is a bit shady. When making this cipher, the length of it should be a perfect square. eg. 4; 9; 16; 25; etc. Now this is how it works. Suppose we use 9 as the length. N B H O A U T D H Since 9 is the lenth, we should make 3 rows of horizontal letters, as follows: N B H O A U T D H Now read it vertically, it should read, NOT BAD HUH.

Why was the Caesar cipher made?
Julius Caesar, of course! It was created for times of war, and it was a very simple cipher indeed.
What is the difference between code and cipher?
cipher is a lower level substitution that works at the level of the individual letters that make up the plaintext A code however is higher level and works at the level of words. Therefore this sentence could be turned into the code '@!:[]{}~+'
What does ciphered mean?
In cryptography a cipher is a code used to encrypt or decrypt a coded message. The cipher is the "key" that unlocks the message. So a message (or computer file) that has been encryption coded has been ciphered and must be decoded (deciphered) before it can be read.
What is the significance of the keyword "ndxoxchwdrghdxorvi" in the context of cryptography?
The keyword "ndxoxchwdrghdxorvi" is significant in cryptography as it is used in the Vigenre cipher, a type of polyalphabetic substitution cipher. This keyword determines the shifting of the alphabets to encrypt and decrypt messages, making it a crucial component in ensuring the security of the encoded information.
Who created the Lorenz cipher?
The Lorenz cipher was developed by C. Lorenz AG company in Berlin. The exact employees responsible for it are unknown. It was implemented in four variants in different machines known as SZ40, SZ42, SZ42A and SZ42B and introduced in 1940 and 1942 respectively. The British cryptanalysts at Bletchley Park referred to the Lorenz cipher as Tunny and broke it by various hand methods (but too late to be of military value) until the first of 10 Colossus programmable electronic digital computers ran in 1944 (the first militarily useful message broke by the Colossus was on June 5, 1944 reporting that the Panzers were being ordered to leave Normandy and go north to Calais, clearing the way for D-Day on June 6, 1944 without having to worry about any Panzers for long enough to capture the beaches and have moved well inland).
