python-2.7 - 如何将私钥作为字符串提供给 paramiko 以进行 ssh 连接？

Question

我正在尝试使用 ssh 使用 Python paramiko 包连接到服务器。

当我尝试使用“pem” key ssh 进入服务器时，它起作用了，但是当我通过在字符串中获取私钥内容来尝试它时，它显示了错误。

使用以下代码:

    import paramiko
    import StringIO
    content="-----BEGIN RSA PRIVATE KEY----- MIIEowIBAAKCAQE ----whatever content"
    private_key = StringIO.StringIO(content)
    k = paramiko.RSAKey.from_private_key(private_key)
    c = paramiko.SSHClient()
    c.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    host="XX.XX.XX.XXX"
    c.connect( hostname = host,username="ec2-user", pkey = k )
    print "Connected to " + host`

我得到以下输出:

Traceback (most recent call last):
  File "one.py", line 6, in <module>
    k = paramiko.RSAKey.from_private_key(private_key)
  File "/home/ec2-user/abc/local/lib/python2.7/site-packages/paramiko/pkey.py", line 217, in from_private_key
    key = cls(file_obj=file_obj, password=password)
  File "/home/ec2-user/abc/local/lib/python2.7/site-packages/paramiko/rsakey.py", line 42, in __init__
    self._from_private_key(file_obj, password)
  File "/home/ec2-user/abc/local/lib/python2.7/site-packages/paramiko/rsakey.py", line 167, in _from_private_key
    data = self._read_private_key('RSA', file_obj, password)
  File "/home/ec2-user/abc/local/lib/python2.7/site-packages/paramiko/pkey.py", line 277, in _read_private_key
    raise SSHException('not a valid ' + tag + ' private key file')
paramiko.ssh_exception.SSHException: not a valid RSA private key file

谁能指出可能出现的问题吗？

私钥文件是一个多行文件。

因此，当将其用作字符串时，请保留内容结构以保持其有效。

content = """-----BEGIN RSA PRIVATE KEY-----
              MIIEpgSIJOBAAKCAQEAqwH5fWIbtFRankLqvtnQ6OKwmIa49i
              ..........................................
              -----END RSA PRIVATE KEY-----"""

private_key = StringIO.StringIO(content)
k = paramiko.RSAKey.from_private_key(private_key)
