From b8bc3e183b43e9aeee8a8f23c8e48fffb6eedc35 Mon Sep 17 00:00:00 2001

Subject: [PATCH 08/34] EP11: Supply CKA_PUBLIC_KEY_INFO when importing private
keys
When importing private keys, the SPKI of the corresponding public key
is returned in parameters csum/cslen of the m_UnwrapKey() EP11 host
library call. Supply this SPKI as CKA_PUBLIC_KEY_INFO to the object.
For public key import, the common code already builds the SPKI from
the clear public key attributes of the imported public key.
