For WEB applications, it is important to secure logins. But most WEB systems are sending plaintext when they send a login password, so it's easy for intruders to hear passwords. Of course, SSL is a good way to implement secure connections, but in many cases we can't set the server to be a WEB server with SSL. Therefore, if you add a
In the actual product service publishing environment, Linux servers generally prohibit the use of remote root account login, only allow the least privileged remote account using SSH login, and then switch accounts to achieve the purpose of Management Server. Let's summarize how to create a secure SSH login account."Ope

I saw a blog post about secure login authentication a few days ago. However, the logon authentication algorithm mentioned in this article is a bit complicated and still has some security defects. I think we can use the HMAC algorithm to perform secure logon authentication for WEB applications.
