SHA-3 is KECCAK

[Chris Cain]

One more thing, if you're curious about taking your first step 
into actually learning the basics of cryptography, you can use 
this:

Dan Boneh is a well respected expert in cryptography and his 
class is very well structured (it wasn't the first one I took, 
but it's definitely comparable to an actual college course on 
cryptography). Do not take it expecting that you'll even be 
remotely capable of going against the recommendations by experts 
by the end (in fact, you'll learn that such things is idiocy if 
you pay any attention to it).

If you do take it, do the assignments and homework. Despite such 
things having the reputation of being just a bother, the 
assignments are necessary to fully understand the material for 
advanced topics like this. They are tough but they'll teach you 
pretty quickly that looking at, for instance, the number of bits 
in crc32 is meaningless for creating attacks.
