Yes, we should probably include it for completeness sake (on this page, or elsewhere). However, I'm not sure if the Lucifer cipher is strong enough, as it is vulnerable to differential cryptanalysis (although that would require a lot more data to work with). stormseeker's comment "the CIA couldn't brute force it" suggests that a fairly strong cipher was used.
