从字符串中提取paramiko中的私钥如何包含？ [英] How to include the private key in paramiko after fetching from string?

问题描述

我正在和paramiko合作，我已经生成了我的私钥，并尝试这样做很好。现在我正在使用基于Django的应用程序，我已经在数据库中复制了私钥。

I am working with paramiko, I have generated my private key and tried it which was fine. Now I am working with Django based application where I have already copied the private key in database.

我将私钥保存在 charField 在Django模型。我在以下代码中遇到问题：

I saved my private key in charField in Django model. I am facing a problem in the following code:

host = "192.154.34.54"
username = "lovestone"
port = 25
pkey = "------" # I saved my key in this string
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(server, username=username, port=port, pkey=?)

在这种情况下应该怎么办？当我将数据库中的 string 存储在 SSH.connect 中时，应该如何传递私钥？

What should I do in this case? How should I pass the private key in SSH.connect while I stored it in string in database?

即使我不能使用IO，即从数据库获取密钥并将其写入文件，然后使用保存的文件对象并传入 from_private_key（cls，file_obj，password = None） 在此输入代码，因为这是web并且它不是通用密钥。每个用户都有自己的私钥。

Even i can't use the IO i.e. fetch the key from database and write it to a file and then use the saved file object and pass into from_private_key(cls, file_obj, password=None) enter code herebecause this is web based application and it is not a generic key. Every user have it's own private key.

推荐答案

您可以使用 StringIO 用于存储私钥和 PKey 的类方法 from_private_key ，因此您将创建 PKey 实例，您可以将其传递给连接方法。

You can use StringIO for creating file-like object with your stored private key and PKey's class method from_private_key, so you will create PKey instance and you can pass it to connect method.
