博主使用的是python2.7，所以和Python3.x略有不同
一、安装 ras
在终端中输入：sudo pip install rsa
二、开始代码
#!/usr/bin/python
# -*- coding: UTF-8 -*-
import rsa
key = rsa.newkeys(3000)
privateKey = key[1]#密钥
publicKey = key[0]#公钥
message = 'alec is a good man'
print '======='
print message
message = message.encode()
cryptedMessage = rsa.encrypt(message,publicKey)#加密
print cryptedMessage
message = rsa.decrypt(cryptedMessage, privateKey)#解密
message = message.decode()
print '==========='
print message
