Missing MACs

[newpavlov]

List of "would be nice to have" algorithms:

• CBC-MAC (Update to cipher v0.4 #103)
• GMAC
• CMAC (OMAC1)
• KMAC
• OMAC2
• PMAC (Parallelizable MAC #2)
• UMAC
• VMAC
• Poly1305 (poly1305 v0.1.0 #14)

It can be changed based on discussion.

What about GMAC?

[newpavlov]

Yes, I should've mentioned it too. List updated.

What about KMAC?

[newpavlov]

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 .

[tarcieri]

I think it would make sense to put those all inside a umac crate, and only factor them into separate crates if there is another application beyond UMAC

i would like to take on the VMAC

[SalusaSecondus]

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 ghash crate?
