Question

你好，

i am writing a code for auto discovery of IP within the network and then 
data transfer using the socket programming in python. I have read the RSA 
and want to implement in the code. i go through to the link where i got 
the code implementation and the whole code for server and client.
Here is the link where the code is:

<https://riptutorial.com/python/example/27170/client-side-implementation>
<https://riptutorial.com/python/example/27169/server-side-implementation>

There are two links and the setup for PyCrypto is.

*PyCrypto (Download Link: https://pypi.python.org/pypi/pycrypto )

*PyCryptoPlus (Download Link: https://github.com/doegox/python-cryptoplus )

我在raspberry pi上尝试了它，并安装了我上面编写的所有基本模块，并使用命令行如下运行它： python3 server.py 但这给了我一些模块相关的错误。

Crypto.Cipher.IDEA isn't available. You're probably using the Debian 
pycrypto version. Install the original pycrypto for IDEA.
Traceback (most recent call last):
File "serverRsa.py", line 10, in <module>
from CryptoPlus.Cipher import IDEA
File "/home/pi/.local/lib/python3.5/site- 
packages/CryptoPlus/Cipher/IDEA.py", line 4, in <module>
import Crypto.Cipher.IDEA
ImportError: No module named 'Crypto.Cipher.IDEA'

我尝试使用pip install PyCrypto并将其与pip3一起使用。然后运行相同的代码，但发生相同的错误。

Actually problem statement is to auto discover of all the nearby ip's 
using the python programming , where i run the code on Raspberry Pi and 
make it as a hotspot and other Pi boards act as client. Now when the 
server found the client or discover them then it register them using some 
key or encryption method.

我只需要使用RSA将某些消息传递给客户端的代码或代码，但是代码似乎有错误。任何人都可以解决此问题。

Answer 1

Crypto.Cipher没有名为 IDEA 的任何属性。

import Crypto.Cipher.IDEA #won't work -_-

也许您正在寻找的是CryptoPlus：

import CryptoPlus.Cipher.IDEA

如果您确实需要Python 2中的IDEA密码，并且速度较慢（比用C语言实现的速度要慢得多）也可以，这里有一个https://pastebin.com/hTn5K3Tx。像这样使用它：

cb = IDEA('2bd6459f82c5b300952c49104881ff48'.decode('hex'))
plaintext, ciphertext = 'f129a6601ef62a47'.decode('hex'), 'ea024714ad5c4d84'.decode('hex')
assert cb.encrypt(plaintext) == ciphertext
assert cb.decrypt(ciphertext) == plaintext

请注意，IDEA的最后一项专利于2012年到期，现在IDEA为free to use for the public。
