We discuss the basic algorithms of {\tt normaliz}, a program for the compuation of integral closures of affine semigroups, or, equivalently, Hilbert bases of finite rational cones. {\normaliz}, developed by R. Koch and the speaker, can also be used to compute the volume and the lattice points of integral polytopes, integral closures of monomial ideals and related objects.
