SHA-3 is KECCAK

[Uranuz]

I support the idea that it would be useful to have an 
implementation or binding for Keccak and may be other crypto hash 
functions. Now all what I found are pycrypto implementation an 
official implementation written with C at 
http://keccak.noekeon.org/. But I was unable to deal with the 
interface of this library. There are a little of comments in the 
code and I couldn't find concrete examples how to use it. Phobos 
simple interface like in std.digest.md would be more suitable for 
casual use. Very often in not needed to tweek all of these 
parameters for algorithm, but needed that it will just work.

I will appreciate for some guidelines if someone tried to bind 
this C implementation for using in D.
