加密，解密和频率分析 - 凯撒密码 [英] Encryption,Decryption and Frequency Analysis-Caesar Cipher

问题描述

如何通过将字符串（明文）和键作为输入来加密。输入字符串中的每个字母都用字母x替换字母表以生成输出字符串（密文）。 x由键表示。

解密如何与加密相反。所以，它通过说一个字符串（密文）和一个键作为输入来工作。这次每个字母用字母x代替字母表以产生输出字符串（明文）。请快速回复上帝保佑。

How encrypt works by taking a string (plaintext) and a key as input. Each letter in the input string is substituted by a letter x places down the alphabet to produce the output string (cipher text). x is represented by the key.
How decryption is the reverse of encryption. so,it works by talking a string (cipher text) and a key as input. This time each letter is substituted by a letter x places up the alphabet to produce the output string (plaintext). please quick response God bless.

推荐答案

我们不做你的作业：这是有原因的。它就是为了让你思考你被告知的事情，并试着理解它。它也在那里，以便您的导师可以识别您身体虚弱的区域，并将更多的注意力集中在补救措施上。



亲自尝试，你可能会发现它不是和你想的一样困难！

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, you may find it is not as difficult as you think!
