What hash? Okio has some of those built in

I know that the jvm has the `CipherSource`  and a `DigestSource` (I think). I didn’t see any of that on multiplatform though.

I’m just getting MD5 checksums.

Did I miss something available in the okio api?

There's also a HashingSink into which you can send the file's contents

I can’t use `ByteString` because the files are potentially very large, and I can’t load the entire file into memory.

I want to read a file contents and get the hash. What can I use as the `Sink` when I don’t actually want to do anything with the data? Is there a NoOpSink or an EmptySink?

There's a blackhole sink, yes. I think it's a top-level factory method

oh - what the heck. I definitely looked for this earlier. I just found `HashingSource` in the common layer too.

Maybe my IDE glitched and didn’t give me proper completion while I was looking for these. Either way - I’m glad okio provides these in a multiplatform way. It’s far more convenient.
