From 8ed49c7675e106bc23f34ac065d8add75e0e2f45 Mon Sep 17 00:00:00 2001 From: Joel Fernandes Date: Tue, 29 Oct 2013 17:37:38 -0500 Subject: [PATCH] crypto: omap-aes - Fix CTR mode counter length NIST vectors for CTR mode in testmgr.h assume the entire IV as the counter. To get correct results that match the output of these vectors, we need to set the counter length correctly.
