然而,针对Caesar Cipher这种基础的加密算法,腾讯云并没有特定的产品或服务。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...
Python中的Caesar Cipher函数 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? ") s...
encrypted = cipher_cipher_using_lookup(text, 3, characters = (string.ascii_lowercase + string.ascii_uppercase), decrypt = False, shift_type="left") print("plain text:", text) print("encrypted text with negative shift:",encrypted) Output: Notice how each of the characters in our plain te...

print "Cipher: " + encrypt(text,s) 输出(Output) 您可以看到Caesar密码,即输出,如下图所示 - 说明(Explanation) 纯文本字符一次遍历一个。 对于给定纯文本中的每个字符,根据规则转换给定字符,具体取决于加密和解密文本的过程。 在执行这些步骤之后,将生成一个新字符串,称为密文。
