Is there any plan to provide this support in future?
I ask this as I have come across an h/w which generates ecx (private) key, returns reference to the private key and the corresponding public key(octet string).
Private key reference instead of actual private key is encoded while storing the key persistently. Public key derived by s/w from this "dummy" private key wouldn't be the correct public key and h/w doesn't have the ability/support to take in the private key reference to generate the public key. This makes savingpublic key along with private key (reference) unavoidable at the time of key generation.
I would like to know how other h/w engines/providers supporting ecx keygen are handling this situation.
