Caligo, an Extensible Block Cipher -and- CHash, a Caligo Based Hash

The Caligo operations are performed on whole blocks only. No subdivision passes through an s-box or a Feistel network. The cipher definition is the same for any block size, allowing exhaustive search for statistical deviations on small block variants. I also propose CHash, a hash function that takes advantage of the cipher extensibility and resists the extension attack.
