Support for KMAC

Open BrianSipos opened this issue 11 months ago • 3 comments

It would be convenient if this library directly supported the cSHAKE and KMAC algorithms from NIST SP 800-185. These algorithms are already implemented as part of PyCryptodome but having them in this library would enable some other synergistic uses within cryptography.

We rely on OpenSSL for core cryptographic algorithms, are these available in OpenSSL?

As of OpenSSL 3 there are EVP APIs for KMAC128 and KMAC256 with an example of use. Don't see a direct cSHAKE use in the API though.

I actually care more about being able to use KMAC than the underlying cSHAKE, so I'll update this ticket to clarify.

We would consider a proposed API + PR for this but are unlikely to design and develop it ourselves.
