X.509: Use verify_signature() if we have a struct key * to use
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. Signed-off-by: David Howells <dhowells@redhat.com>
