I’m hopeful for the same thing. I’ve seen a number of people looking to embed other crypto libraries like mbed TLS in their application, but that uses a lot of space and doesn’t use the hardware crypto.
From some topics I’ve read a lot of the libraries might currently be pruned out of the firmware during compile currently though. I’ve opened Feature Request: DTLS support because it seems this support should be easily included as it’s being used.
I haven’t tried it yet, but I hear if you compile a monolithic firmware you should be able to access everything.
