From ac026f4668d031220b3203913005c0ded0a38e1d Mon Sep 17 00:00:00 2001 From: Marko Kovacevic Date: Fri, 2 Nov 2018 09:55:33 +0000 Subject: [PATCH] examples/fips_validation: support CMAC parsing Added enablement for CMAC parser, to allow the application to parser the cmac request files and to validate all test types supported.
