This is MuCipher. MuCipher is a small library intended for ciphering short bits of text in such a way that they can only be decided by running them in any Haskell interpreter. Example $ ghci Prelude> import Codec.MuCipher Codec.MuCipher> printCipher "Hello World" showIntAtBase 8 (" HWdelor"!!) 1706569195 "" Codec.MuCipher> Have Fun!
