凯撒密码(Caesar Cipher)是一种简单的替换密码,它通过将明文中的每个字母按照一个固定的偏移量进行替换来加密消息。在Python中,我们可以使用以下代码实现凯撒密码的字符替换: 代码语言:txt 复制 def caesar_cipher(text, shift): encrypted_text = "" for char in text: if char.isalph
在使用Caesar Cipher时,您可以通过使用Python 3编程语言实现自己的加密和解密函数,而无需依赖特定的云服务商产品。 下面是一个使用Python 3实现Caesar Cipher的示例代码: 代码语言:txt 复制 def caesar_cipher(text, key): result = "" for char in text: if char.isalpha(): if char.isupper(): result +=...

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? ") ...
