[PATCH 05/10] KEYS: Add identifier pointers to public_key_signature struct

From: David Howells
Date: Wed Oct 21 2015 - 11:14:15 EST


Add key identifier pointers to public_key_signature struct so that they can
be used to retain the identifier of the key to be used to verify the
signature in both PKCS#7 and X.509.
