Ciphertext :The resulting message formed when an encryption algorithm is applied on the plaintext. Shift :Integer between zero and twenty-five which can tell us how many shifts will be applied on a character.

在密码学中,恺撒密码(英语:Caesarcipher),或称恺撒加密、恺撒变换、变换加密,是一种最简单且最广为人知的加密技术。它是一种替换加密的技术,明文中的所有字母都在字母表上向后(或向前)按照一个固定数目进行偏移后被替换成密文。例如,当偏移量是3的时候,所有的字母A将被替换成D,B变成E,以此类推。这个加密方法...
解密:将混乱的信息转换为其原始形式。...Cipher密码:一种用于执行加密或解密的算法,通常是一组可履行的、定义明确的步骤。【密码学】在以前是加密的同义词,即把信息从可读的格式转换为毫无意义的信息的过程。...加密技术的历史可以追溯到古埃及,历史十分悠久。举例来说,Caesar Cipher凯撒密码是凯撒大帝用来与将军们...
An example plaintext to ciphertext using Atbash: In the affine cipher the letters of an alphabet of size m are first mapped to the integers in the range 0..m - 1. It then uses modular arithmetic to transform the integer that each plaintext letter corresponds to into another integer that ...
The Caesar cipher, also known as a shift cipher, is one of the simplest forms of encryption. It is a substitution cipher where each letter in the original message (called the plaintext) is replaced with a letter corresponding to a certain number of letters up or down in the alphabet.Learn...
