Implementation of KangarooTwelve in Go

😳 Hello you!

I'm David Wong. I'm a founder of zkSecurity. I was previously a cryptography engineer working on the Mina cryptocurrency at O(1) Labs. I'm also the author of the book Real-World Cryptography. I used to be the security lead on the Diem blockchain (formely known as Libra), working from Novi (Facebook). Before that I was a security consultant at Cryptography Services (NCC Group).

You can find more about what I do on my crypto blog cryptologie.net or my portfolio davidwong.fr.

gokangarootwelve's Issues

Not an issue but more of a general question

In the example of K12Sum...

Is there a way we can do a K12-256/512 and whatever flavors of the world?

If so, I can probably write that and push you the information.
just wanted to know if hash.Read(out) being []byte, 32 was the 256 edition...

Applying K12's "vine" construction to other sponges

Is it possible to generalize KangarooTwelve to the Vine construction ("leaves staple to a pole") for SHA3 competition round 2 candidates (reduced Fugue, Hamsi and Luffa)? And JH and CubeHash are not necessary since they are proven to be too insecure.
note: BLAKE has been modified into NORX, and Skein is a semi-sponge so there are potential as well.

Switch state after first read

	hash := K12.NewK12(nil)
	buf := make([]byte, 32)
	hash.Write(buf)
	hash.Read(buf)
	hash.Read(buf)

causes panic because sponge thinks we are still spongeAbsorbing
