Question

我想做一个密码，最后用RSA加密。这是我到目前为止的情况。在

    time.sleep(1)

os.remove('encryptedfile.txt')

我的错误出现在第57行，错误信息如下：

^{pr2}$

但是，当我运行RSA部分时，我没有得到一个错误。RSA部分如下：

import Crypto
from Crypto.PublicKey import RSA

#Quick way to generate a new key
private_key = RSA.generate(1024)

#Show the real content of the private part to console, be careful with this!
print(private_key.exportKey())

#Get the public part
public_key = private_key.publickey()
with open("rsa.pub", "w") as pub_file:
    pub_file.write(public_key.exportKey())

with open("rsa.pvt", "w") as pvt_file:
    pvt_file.write(private_key.exportKey())

#Load public key back from file and we only need public key for encryption
with open('rsa.pub', 'r') as pub_file:
    pub_key = RSA.importKey(pub_file.read())

#Encrypt something with public key and print to console
encrypted = pub_key.encrypt('hello world', None) # the second param None here is useless
print(encrypted)

我使用的是安装在Windows7上的Python2.7.3和Crypto2.6.1。在
