This is more of a request than an issue..
I was wondering if you could spit out some test vectors for KMAC128 and KMAC256.

If so I can interop against them in openssl.

Cheers

Java 9 should have the keccak algorithm built in. I'll try to throw something together.

Thanks for that..

In the file where I pull in your data and reformat it, I have just put this reference to your wiki in...

#There are currently no official test vectors for Single Step KDF

Are you ok with this?

Are you ok with this?

Sure :)

(link to openssl PR for reference: openssl/openssl#8230)

Btw: you could generate your own test vectors (and modifying the output format), by using https://github.com/patrickfav/singlestep-kdf/blob/master/src/test/java/at/favre/lib/crypto/references/TestVectorGen.java

Hmmm I dont think KMAC is supported in java
I cant seem to see KMAC in the mac algorithms (at least in the jdk9 docs)

You are mostly correct. SHA-3 is implemented in Java9, but not SHAKE*, cSHAKE or KMAC unfortunately. Will have to resort to 3rd party libs.
