Nuts are shelled by soaking in water (salt water, probably) for 24 hours, then the nuts are boiled for 5 minutes. The boiling softens the shell, and makes cracking (by hand or machine) much easier. Nuts that are to be sold as blanched or sliced nuts, may be boiled again, before blanching and/or slicing.
