I am not going to comment on how bad this all is, because you all know… Let’s just insert some eye rolling here...

As far as I understand the documentation this package implements a lot of hashes, but none of them are enabled by default. They need to be enabled whenever they are needed.

The “features” option enabled “shake” here. This is basically how to enable the hash that you need. In the example above, sha3 has been used.

> I can't figure out how to tell the rust compilation of tiny-keccak to specify the various hash functions and in terms of the const-random-macro crate to specify the shake hash function. I would have expected that by default it would specify all of the available hash functions. Also it seems to me that the compilation command includes a list of the hash functions

I would assume that there is nothing that you should do manually here. The people who depend on this package need to tell it which hash they want to use and Cargo is supposed to take care of the rest. In Cargo.toml, there should be something like this:

  [dependencies]
  tiny-keccak = { version = "2.0.0", features = ["sha3"] }

Maybe the syntax has changed? Because the snippet that you posted seems to carry the same information, just in a different format.

I hope I could help :)
