Starting with util-linux commit v2.23-rc1~701 back in 2012, losetup does not support encryption, so it cannot make use of hashalot in any plausible way.
util-linux-2.36.1-alt3 -> sisyphus: Wed Jul 28 2021 Alexey Gladkov <legion@altlinux.ru> 2.36.1-alt3 - losetup cannot use hashalot package and therefore should not require it (ALT#40590).
