Luffa: Another SHA-3 candidate hash that’s also a stream chiper

I have listed before some hash functions that also work as stream ciphers; it would appear that the SHA-3 submission Luffa is a hash function that can output an arbitrarily long hash and be used as a stream cipher.

Also, LUX and MeshHash appear to have some cryptographic weakness and neither made it to round two of the SHA-3 competition; Luffa, however, did make it to round 2.
