Dear all,
we've come across a strange behaviour of the pkcs15-lib in OpenSC when
we generate an EC key pair:
After generating an fresh EC key pair, our code returns a
sc_pkcs15_pubkey containing the EC public key and DER encoded domain
parameter. The public key is then encoded in sc_pkcs15init_generate_key
and added to the DF in the framework when it's immediately decoded again.
During this encode / decode step the domain parameter are lost.
I'm wondering why this encode / decode step is done ?
If it is required for some reason, then I would rather encode the public
key in SubjectPublicKey structure that would also preserve the domain
parameter in AlgorithmIdentifier.
