一 代码

1. import rsa
3. key = rsa.newkeys(3000)#生成随机秘钥
4. privateKey = key[1]#私钥
5. publicKey = key[0]#公钥
7. message ='sanxi Now is better than never.'
8. print('Before encrypted:',message)
9. message = message.encode()
11. cryptedMessage = rsa.encrypt(message, publicKey)
12. print('After encrypted:\n',cryptedMessage)
14. message = rsa.decrypt(cryptedMessage, privateKey)
15. message = message.decode()
16. print('After decrypted:',message)

二 运行结果

Before encrypted: sanxi Now is better than never.

After encrypted:
