python RSA 非对称加解密的实现

import rsa
# key = rsa.newkeys(3000)#生成随机秘钥
# print(key)
# privateKey = key[1]#私钥
# publicKey = key[0]#公钥
publicKey,privateKey = rsa.newkeys(512)

print("---------------------publickey-----------------------------------")
print(publicKey)
print("--------------------private----------------------------")
print(privateKey)

print("----------------------------------------------------------------")
message ='今天是个好天气.'
print('Before encrypted:',message)
message = message.encode('utf-8')
cryptedMessage = rsa.encrypt(message, publicKey)
print('After encrypted:\n',cryptedMessage)
message = rsa.decrypt(cryptedMessage, privateKey)
message = message.decode('utf-8')
print('After decrypted:',message)
