The default cipher for LUKS is nowadays, i.e. AES as cipher and XTS as mode of operation. This should be changed only under very rare circumstances. The default is a very reasonable choice security wise and by far the best choice performance wise that can deliver between 2-3 GiB/s encryption/decryption speed on CPUs with AES-NI. XTS uses two AES keys, hence possible key sizes are  and.
