From 6789b2dc455b90efc9c88886c9366adc9abb7347 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 6 Jul 2005 13:52:27 -0700 Subject: [PADLOCK] Move fast path work into aes_set_key and upper layer Most of the work done aes_padlock can be done in aes_set_key. This means that we only have to do it once when the key changes rather than every time we perform an encryption or decryption. This patch also sets cra_alignmask to let the upper layer ensure that the buffers fed to us are aligned correctly. Signed-off-by: Herbert Xu Signed-off-by: David S.
