在load_pub_key中访问文件 [英] File accessing in load_pub_key

问题描述

考虑以下代码:

fileHandle = open ( 'test8.pem','w' )
fileHandle.write (data)
pub_key = M2Crypto.RSA.load_pub_key(open('test8.pem'))

哪个会产生以下错误:

 File "/usr/lib/python2.4/site-packages/M2Crypto/RSA.py", line 343, in load_pub_key
bio = BIO.openfile(file) 
  File "/usr/lib/python2.4/site-packages/M2Crypto/BIO.py", line 186, in openfile
    return File(open(filename, mode))
IOError: [Errno 2] No such file or directory: ''

如何将文件传递到load_pub_key方法中，以便只需传递文件名即可访问它?

How do I pass the file into load_pub_key method so it can be accessible by simply passing the file name?

推荐答案

我也有同样的问题.我尝试加载文件处理程序而不是路径，但没有帮助.

I also have the same issue. I tried loading a file handler instead of path but it didn't help.

锻炼的事情是使用M2Crypto的X509模块.您可以尝试使用以下功能来获取公钥实例:

The thing that workout was using X509 module from M2Crypto. You can try use this functions to obtain a public key instance:

certificate = M2Crypto.X509.load_cert(cert_path)
pubkey = certificate.get_pubkey()
