Hi


I have done this using a micro controller

Over voltage protection - use a zener diode to short the FB input when breakdown

Over current - you can measure the current via a current sense resistor and add it to the feedback loop or trigger a uc interrupt

The same for short circuit

All the best

try to look for voltage regulators with over current protection, those circuits theoretically may help your design
