``` module Crypt_Discordian where```

``` import List vowel_list = "aeiouAEIOU" is_vowel c = c `elem` vowel_list move_vowels lis = move_vowels' lis [] [] move_vowels' [] c v = v ++ c move_vowels' (x:xs) c v | is_vowel x = move_vowels' xs c (x:v) | otherwise = move_vowels' xs (x:c) v remove_spaces str = filter (\x -> x /= ' ') str encrypt str = List.sort \$ move_vowels \$ remove_spaces str {- The algorithm for Discordian text encryption is given at: http://www.principiadiscordia.com/book/78.php After implementing this, I realized that all the early steps are a farce. But anyway, here is the algorithm in case you don't enjoy tilting your head to read a page: Step 1. Write out message (HAIL ERIS) and put all vowels at the end (HLRSAIEI) Step 2. Reverse order (IEIASRLH) Step 3. Convert to numbers (9-5-9-1-19-18-12-8) Step 4. Put into numerical order (1-5-8-9-9-12-18-19) Step 5. Convert back to letter (AEHIILRS) This cryptographic cypher code is GUARANTEED TO BE 100% UNBREAKABLE .. so says the Principia Discordia. But I think we can generate and test to break it. Many thanks to kosmikus and Pseudonym for their help in developing this module -} {- Discordians. They are a group of people who believe that spirituality is as much about disharmony as it is about harmony. So, in their primary book, Principia Discorida: http://principiadiscordia.com/ you never know what is serious and what is play. The wikipedia has more to say on them: http://en.wikipedia.org/wiki/Discordian -} ```
