An algorithm to solve the Caesar Cipher problem. Columnar Transposition involves writing the plaintext out in rows and then reading the ciphertext off in columns.

In its simplest form it is the Route Cipher where the route is to read down each column in order.

. We work out values of letters then do the calculations before converting numbers back to letters. For example the plaintext a simple transposition with 5. Thus the ciphertext produced is IHHWVC SWFRCP.

To do this first find the determinant of our key matrix. This particular cipher is aptly known as the Caesar Cipher more on that in a couple of minutes. This modified cipher uses an alphabet that is out of order.

This was created to help decrypt the Kryptos sculpture. In contrast to modern cryptographic algorithms most classical ciphers can be practically computed and solved by hand. To decrypt the data using the Hill Cipher first we need to find the inverse of our key matrix.

An earlier encryption technique which used to substitute the current alphabets with alphabet after a number of count. However they are also usually very simple to break with modern technology. Decryption In deciphering the ciphertext we must perform the opposite or inverse functions on the ciphertext to retrieve the plaintext.

The affine cipher with a 5 b 8. In cryptography a classical cipher is a type of cipher that was used historically but for the most part has fallen into disuse. Two keys are used.

Once again the first. Instead of repeating the password used in order to encrypt text this uses the password once and then the plaintext. One creates the alphabet the second is the encoding passphrase.

The Cipher by Isabella Maldonado is a nail-biting race against time POPSUGAR Maldonado does a superb job of depicting a woman whos made a strength out of trauma and an even better job at showing how a monster could use the internet to prey on the vulnerable. However there have been other types of symmetric ciphers that have existed throughout history including everything from the Vigenère Cipher which dates back to the 1500s to the modern AES algorithm more on that later. In our case determinant evaluates to 37 which is again greater than 26 so we will find mod26 of out determinant ie 37 11 mod 26.
