caesar cipher

password was invented by Leon Batista in 1568, and the famous Virginia and Beaufort passwords are multiple tables instead of passwords. Below we introduce a typical single form substitution password--Caesar (Caesar) password, also called the cyclic shift password. The encryption method is to replace each letter in the plaintext with the letter r of the letter in the alphabet to achieve the purpose of encry

Description: Julius Caesar lives in times of danger and intrigue. In order to survive, he invented the password for the first time for the army's message delivery. Suppose you are an officer in the Caesar Corps who needs to decipher the message sent by Caesar and provide it to your general. Message encryption means that each letter in the original message is repl

The ancient Roman Emperor Caesar used the following methods to encrypt military intelligence during the war: please write a program that uses the above algorithm to encrypt or decrypt the user input of the English string requirements design ideas, program flowchart, source code, results.Design idea: Enter a string, and then each character is taken separately, and the algorithm of the character is added 3, forced to convert to the following 3 character

In cryptography, the Caesar password (also known as Caesar encryption and Caesar transformation) is the simplest and most widely known encryption technology. It is a technology to replace encryption. All the letters in plain text are shifted backward (or forward) to a fixed number in the alphabet and then replaced with a secret. For example, when the offset is 3,

Ancient Cipher Specified ent Roman Empire had a strong government system with varous parameters, including a Secret Service Department. important documents were sent between provinces and the capital in encrypted form to prevent eavesdropping. the most popular ciphers in those times were so called substitution cipher and permutation cipher. substitution

You can send this poem to your girlfriend. If she is smart, she will surely see that it is a Tibetan poem, so that she can understand your mind. In fact, Tibetan poetry is an encryption technique that hides the secret by means of coordinate transformation. Although this example is very s

The block cipher has a certain size as the base unit for each processing, while the sequence cipher is an element (a letter or aBITS) as a basic processing unit. A sequence cipher is an encrypted transformation that changes over time and has a conversion speedThe advantages of fast and low error propagation, the hardware implementation of the circuit is more simp

In cryptography, Caesar's code (or Caesar's encryption, Caesar's transformation) is one of the simplest and most widely known cryptographic techniques. It is a technique for replacing encryption, in which all letters in plaintext are replaced by a fixed number of Cheng Mi-wen (or forward) after the alphabet is offset. For example, when the offset is 3, all the letters A will be replaced with D,B into E, and so on. This method of encryption was named after Ca
