Safety | design 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
