Question

我最近还没有更新任何我认为会影响nacl和paramiko签名过程的内容，但现在它不会起作用。我重新安装了paramiko和netmiko并确保所有加密库都是最新的。我不知道还有什么可做的，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。这段代码就是设置设备定义的原因。

以下是与设备创建和ssh连接打开相关联的堆栈跟踪。

经过对密码学和后续模块的大量修补，我刚刚安装了所有相关的库和现在的工作。不幸的是，不确定它是如何进入这个状态的，但重新开始更容易。

Answer 2

除非您发布代码，否则需要进行一些猜测：

也许问题类似于https://github.com/mitmproxy/mitmproxy/issues/2372，它通过在版本1.9中安装cryptography包来解决。

使用Paramiko时出现加密错误？
