hmac_SHA-256_function.kt

Hey folks, I am currently working on a multiplatform library for android/ios involving some hashing. As part of this I need a hmac function using SHA-256. Above you can see the implementation I have for the JVM, now I wonder how I can implement this using Kotlin/Native.

I found this swift example (<https://gist.github.com/thewheat/7342c76ade46e7322c3e#gistcomment-1769792>), which does more or less what I need, despite it gives me a `String` instead of a `ByteArray`, but I am still a bit lost what are the required steps.

Since the above linked swift example just requires `Foundation`, should I try to convert this to kotlin in the native platform source set?

Thanks in advance.
