"Have to" is used to show obligation. "Must" has the same meaning but cannot always be replaced by "have to".
I have to wash the dishes because my girlfriend wants me to.
In the negative form, we use "don't have to" to say that there is no obligation, but we use "mustn't" to say there that there is a strong obligation to NOT do something.
My friend doesn't have to go to work tonight, so we're going to go to a party. You mustn't cheat on your test, or your teacher will be angry.
