“exportKey”功能不pycrypto-2.6.1（蟒蛇2.7.6）ubuntu14.04 LTS

Question

你好，我试图运行这个简单的代码来生成私钥认可得到这个错误：

Traceback (most recent call last): 
    File "erase-this.py", line 5, in <module> 
    f.write(RSA.exportKey('PEM')) 
AttributeError: 'module' object has no attribute 'exportKey' 

我里面/pycrypto-2.6.1/lib/Crypto/PublicKey检查，功能

def exportKey(self, format='PEM', passphrase=None, pkcs=1): 

存在内部RS A.py.

是否有人知道我为什么会得到错误：

AttributeError: 'module' object has no attribute 'exportKey'??? 

Answer 1

exportKey()是关键，而不是一个模块功能的方法。所以你需要做

f.write(key.exportKey('PEM')) 

这是一个简短的演示（使用较小的关键尺寸）。

#!/usr/bin/env python 

from Crypto.PublicKey import RSA 
key = RSA.generate(1024) 
print key.exportKey('PEM') 

pub_key = key.publickey() 
print pub_key.exportKey('PEM') 

典型输出

-----BEGIN RSA PRIVATE KEY-----
