作为一个小型(大型)业余爱好项目,我已着手在C#中创建一个(非常原始的)ssh-2.0客户端.这是为了探索和更好地理解DH,并帮助我的加密熟悉:)

根据RFC 4253,我已经开始了这样的初始连接:

(省略不相关的变量预设等)

Random cookie_gen = new Random();
while ((ssh_response = unsecure_reader.ReadLine()) != null)
{
   MessageBox.Show(ssh_response);
   if (ssh_response.StartsWith("SSH-2.0-")
   {
      // you told me your name, now I'll tell you mine
      ssh_writer.Write("SSH-2.0-MYSSHCLIENT\r\n");
      ssh_writer.Flush();
      // now I should write up my supported (which I'll keep to the required as per rfc 4253)
      ssh_writer.Write(0x20); // SSH_MSG_KEXINIT
      byte[] cookie = new byte[16];
      for (int i = 0; i < 16; i++)
         cookie[i] = Convert.ToByte(cookie_gen.Next(0, 10));
      ssh_writer.Write(cookie); // cookie
      // and now for the …
