<Ack about licensing. The idea wouldn't be to copy the code, but to learn how to implement message digests and HMAC on top of OpenSSL 3.0.8.>
Implementing the OpenSSL 3 API and exposing OpenSSL HMAC functionality in commons-crypto are things I've wanted to engage on for a while now. I was involved in the commons-crypto OpenSSL 1.1.x upgrade so I have some familiarity with the code base, albeit dated. The reason that neither the OpenSSL 3 API nor the HMAC functionality have been added to commons-crypto yet, IMHO, is because both are non-trivial efforts and we all have day jobs. Until now, there hasn't been much of an ask for either feature, but considering the recent chatter maybe there's enough interest to generate some momentum. I would be happy to collaborate on this effort if it gains traction.
