Phil Karn described a construction for turning any hash function into the core of a Feistel cipher in 1991. So far as I can tell, such ciphers are actually quite secure, though impractically slow. Pointers to his original sci.crypt posting would be appreciated, I wasn't able to find it with a quick search. Perry -- Perry E.
