What about GMAC?
newpavlov commentedon Dec 29, 2017
Yes, I should've mentioned it too. List updated.

What about KMAC?

Updated list with KMAC.

I think I would want to give UMAC a try, but before I start a quick question. Since UMAC uses several different hash-functions, e.g. L1, L2, L3, NH, neither I guess would ever be used by themselves, should I implement them as functions inside a UMAC crate or create smaller crates in https://github.com/RustCrypto/hashes ? Also: quite new to rust, doing this to learn .

I think it would make sense to put those all inside a
umaccrate, and only factor them into separate crates if there is another application beyond UMACmahmudsudo commentedon Oct 24, 2024
i would like to take on the VMAC

I think that I'd like to take on GMAC. It looks like a gentle introduction to contributing directly to RustCrypto.

@SalusaSecondus sounds good, I assume you’re planning to use the
ghashcrate?SalusaSecondus commentedon Apr 4, 2026
@tarcieri , absolutely. My first pass is also only going to target 128 bit tags. I figure get something working and then work with you all to close the remaining gap. I am very much using this as a learning opportunity so that I can hopefully contribute more in the future.

@tarcieri I would like to take up KMAC, I'm thinking of implementing the standard fixed length MAC first and then tackle the XOF mode if thats fine? I'll also spend a good amount of time on trying to implement left_encode and right_encode, this will be my first time working with
#![no_std].tarcieri commentedon Jun 4, 2026
There's already a PR open for KMAC: #221
Pranavjeet-Naidu commentedon Jun 6, 2026
Welp, is there any of the MACs you would recommend I take on? I don't see any work done for VMAC and OMAC2. I was hoping to contribute and use this to help me learn.
