Hasps and Bolts: The Hardware That Makes a Padlock Worth Having
A hasp is the bracket that gives a padlock something worth locking. Get this wrong and the best padlock in the world hangs off a flimsy loop that a screwdriver can pry. The things to look at are the metal and thickness, whether the mounting screws are hidden when the hasp is closed, and whether the hinge is strong enough that it does not become the pry point.
Staple size matters too, since it sets the shackle you can use. A swivel-staple hasp gives you a little play during install on doors that are not perfectly square, which is more useful than it sounds on an old shed.

Choosing well
Mount it into solid material, use the right length screws, and confirm your padlock shackle passes cleanly through the staple. A good hasp is quiet insurance; it just sits there until the day it earns its keep.
