Moodle Quiz Password Changer

There are 2 types of this application, namely those that are installed on the Moodle server (written in C language and then compiled into machine language) and those installed on the Android cellphones of the test supervisors / teachers.

Every few minutes (say every 5 minutes) the password quiz on the Extra restrictions on attempts menu is changed automatically by the application on the server side. This app is run every minute by a cronjob.

The exam supervisor / teacher can find out the latest password from the numbers displayed on his cellphone. There is no need for access to the internet so it can still work on cellphones that don't get a wifi signal / no data packets.
The password that appears, depends on the "salt" (a kind of password) and the duration specified by the Moodle admin. Thus, the password on the school server A is not necessarily the same as the password on the school server B. If the admin suspects that the "salt" is leaking and is known to the students, then the admin simply changes the salt on the server and on the cellphone of each exam supervisor / teacher.

This application is free to be used by anyone, wherever they are. Written in English. The trial version can be used forever, but there is a limit that only one quiz can be changed at a time. While the Android application can be downloaded on Google Play.

Android apps running on the user side, still need 64 bit Linux apps installed on the server. The server side application can be downloaded at:
