让我们深入探讨一下凯撒密码(Caesar Cipher)这一古老且富有魅力的加密技术。凯撒密码基于移位密码的原理，它是一种简单的替换加密方法，通过单表对应的方式，确保了信息的可逆性。加密的核心公式是：f(a) = (a + N) mod 26，其中a代表原始字母，N是位移数，解密则使用相反的移位量：f(a) = (a ...
Caesar Cipher Programming Algorithm in C++. In cryptography, a Caesar cipher, also known as shift cipher, Caesar's cipher, Caesar's code or Caesar shift, is one of the simplest and most widely known encryption techniques. It is a type of substitution cip
