Python Cypto：AttributeError："函数"对象没有属性"加密"

Question

我的代码是：

import Crypto
from Crypto.PublicKey import RSA
from Crypto import Random
random_generator = Random.new().read
key = RSA.generate(1024, random_generator) #generate public and private keys
publickey = key.publickey # pub key export for exchange
encrypted = publickey.encrypt('encrypt this message', 32)
#message to encrypt is in the above line 'encrypt this message'
print ('encrypted message:', encrypted) #ciphertext
f = open ('encryption.txt', 'w')
f.write(str(encrypted)) #write ciphertext to file
f.close()
#decrypted code below
f = open ('encryption.txt', 'r')
message = f.read()
decrypted = key.decrypt(message)
print ('decrypted', decrypted)
f = open ('encryption.txt', 'w')
f.write(str(message))
f.write(str(decrypted))
f.close()

输出错误为：

Traceback (most recent call last):
File "C:UsersvinayDesktopDIATProgramsPython2018-10-08-RSA-sample.py", line 10, in <module>
encrypted = publickey.encrypt('encrypt this message', 32)
AttributeError: 'function' object has no attribute 'encrypt'

Answer 1

你应该使用公钥函数
生成一个密钥publickey = key.publickey()
