For ED25519, I did the parsing and retrieved the private key, but I cannot successfully import it. Reading the status of various PRs, I am not sure whether ED25519PH is actually supported. Or maybe I am doing it wrong and not setting the attributes correctly. I could really use a sample for that!

Mbed TLS does not yet support EdDSA. We do plan to add it, and a community member has even written an implementation, but it's stuck due to a lack of review bandwidth.
