Just wrapped up a little Swift library wrapping the BLAKE3 hash function. I forked @joshuab.rest's library and added conformance to swift-crypto's HashFunction to make it interop with existing digests.

Check it out if you're interested in a pretty fast hash function

Anyway, all this goes to say... CryptoKit's HashFunction API surface doesn't seem to really clearly document a way to duplicate or "fork" a hash state.

I could understand the CryptoKit folks thinking "There is not a great reason for that" but I think there are a few.

Apple's CryptoKit Hash APIs are interesting. `finalize` on HashFunction is not a `mutating` function. So it doesn't put the HashFunction in a non-reusable state. It behaves like it creates a copy of the state then finalizes it.

But the docs say "don't do that".

Genau, mit cryptographic hashfunction (CHF) zusammen ergibt das Sinn

What Is An Address

Was setting up a node and wondered, what's an address? It's not just a string, it's a hash of a pub key. Change my mind. 📈💡

What Is An Address

Was setting up a node and realized, what's an address, really? Just a hash of a pubKey. Don't @ me. 🚀💻

yeah, and then may be go on to manipulate the hashfunction with it. As its done on the filename.
