While the page you linked is quite old, it still works (I tried 2.0.2 version even). (Loop devices are now allocated automatically, no need to use losetup with cryptsetup, just use file as the argument. THe size calculation is too tricky there, it can be simplified.). Are you sure that your *.iso image was correctly created? It seems to me that it is just LUKS header without data (that's why "beyond offset" error).
