凯撒加密(Caesar cipher)是一种简单的消息编码方式:它根据字母表将消息中的每个字母移动常量位k。举个例子如果k等于3,则在编码后的消息中,每个字母都会向前移动3位:a会被替换为d;b会被替换成e;依此类推。字母表末尾将回卷到字母表开头。于是,w会被替换为z,x会被替换为a。 凯撒加密算法实现 package com.jianggujin
凯撒密码@叶海亚Caesar cipher Algorithm Java Encryption with Caesar code 是一种简单的替换(一个字母替换另一个)。 凯撒代码 remplace 是一个字母表移位:字母表中更远的一个字母。

The Caesar cipher is a technique in which an encryption algorithm is used to change some text for gaining integrity, confidentiality, or security of a message. In cryptography there are many algorithms that are used to achieve the same, but Caesar cipher is the earliest and easiest algorithm us...
