我最近没有更新任何我能想到的会影响 nacl 和 paramiko 签名过程的东西，但现在它不起作用。我已经重新安装了 paramiko 和 netmiko，并确保所有的加密库都是最新的。我不知道还能做什么，有什么想法吗？

from netmiko import ConnectHandler
...
def main(device_list):                                        
    username = input("\nWhat is your username? -> ")          
    password = getpass.getpass("\nWhat is your password? -> ")
    for host in device_list:                                  
        juniper_device = {                                    
        'device_type': 'juniper',                             
        'ip': host,                                           
        'username': username,                                 
        'password': password,                                 
        'verbose': False                                   
    }

Netmiko 使用 Paramiko 库建立 SSH 连接。这段代码用于设置设备定义。

这是与设备创建和 ssh 连接打开相关的堆栈跟踪。

在对密码学和后续模块进行了大量修改之后，我刚刚安装了所有相关的库，现在一切正常。不幸的是，不确定它是如何进入这种状态的，但重新开始会更容易。

除非您发布代码，否则需要一些猜测：

也许问题类似于https://github.com/mitmproxy/mitmproxy/issues/2372，通过cryptography在 1.9 版中安装包解决了它。
