Khazad). KHAZAD was presented at the first NESSIE
workshop in 2000, and, after some small changes, was selected as a finalist in the project.
KHAZAD has an eight-round

.
The authors have stated that, "KHAZAD is not (and will never be) patented. It may be used free of charge for any purpose."
Frédéric Muller has discovered an attack which can break five of KHAZAD's eight rounds. No attacks better than this are known as of August 2009.
