Subject: [RFC PATCH 06/12] X.509: Use verify_signature() if we have a struct key * to use [ver #3]
Date: Wed, 09 Mar 2016 11:18:57 +0000	[thread overview]
Message-ID: <20160309111857.28811.33291.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <20160309111814.28811.95697.stgit@warthog.procyon.org.uk>

We should call verify_signature() rather than directly calling
public_key_verify_signature() if we have a struct key to use as we
shouldn't be poking around in the private data of the key struct as that's
subtype dependent.
