Right ? Jim looks for a hex encoded version of the ciphertext returned by binary() in the ASCII ciphertext. Assuming that this substring is long enough that a false positive can be excluded, then either split() must unify the case and set FMT_SPLIT_UNIFIES_CASE, or valid() must accept just one version (usually either all upper case or all lower case), and reject all other versions (and FMT_SPLIT_UNIFIES_CASE must not be set).
