AES-CMAC support in JS

[marczeugs]

It seems like the WebCrypto provider does not currently support AES-CMAC. Is there a way to use AES-CMAC from KMP code with a JS target?

Using the default CryptographyProvider, trying to get AES.CMAC results in Algorithm not found: [object Object].

Yes, that's correct. The WebCrypto API has a list of supported algorithms.

Is there a way to use AES-CMAC from KMP code with a JS target?

It might be possible to implement it from scratch or use a JS library, but I'm not sure that either of those will be incorporated into cryptography-kotlin.

I envision that in the future, an OpenSSL-based provider might be compiled to Wasm and used in web targets (js and wasm-js). But it will not happen soon, for sure.

Ah, thanks for the explanation. I was searching around and found examples that use AES-CMAC using WebCrypto, like here for example: https://github.com/diafygi/webcrypto-examples

Then I assume support was dropped at some point. I will try to find a JS library then, thanks!
