Do you mean the FMT_SPLIT_UNIFIES_CASE? That flag should be set if (and only if) your format has a split() that returns the ciphertext with case unified (to lower or upper, I think we normally use lower). So the raw format with hex encoding could/should unify case while the Cisco version must not do that (since it would ruin the base64).

The reason for unifying is so John can recognize that a hex hash of DEAD3137CAFE is cracked even though the pot file has it as dead3137cafe.
