Caesar Cipher(凯撒密码)是一种简单的替换密码,属于对称加密算法。它通过将每个字母按照固定的偏移量进行替换来加密文本。这个偏移量通常被称为“密钥”,并且在加密和解密过程中需要保持一致。 Caesar Cipher的加密过程很简单。对于每个字母,将其替换为字母表中偏移量为密钥的字母。例如,如果密钥为3,则'A'将被替换为...
我正在尝试在Python中创建一个简单的Caesar Cipher函数,它根据用户的输入移动字母,并在最后创建一个最终的新字符串。唯一的问题是最终的密文只显示最后一个移位的字符,而不是一个包含所有移位字符的整个字符串。 这是我的代码: plainText = raw_input("What is your plaintext? ") ...

Coding in Python def generate_key(n): letters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ" key = {} cnt = 0 for c in letters: key[c] = letters[(cnt + n) % len(letters)] cnt += 1 return key def encrypt(key, message): cipher = ""
It looks like the message might be encrypted with something called a Caesar cipher, where all the letters are shifted in the alphabet by some amount. We'll need to give Python the power to find the true meaning of the words "Ncevy," "gpvsui," "ugflgkg," and "wjmmf"....

Create a function to loop through all letters in a word and decipher the entire word by using a Caesar cipher.
Python实现凯撒密码加密解密 凯撒密码(Caesar cipher),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...
