From e1147d8f47eb8fef93f98a30858192145137d2b2 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Mon, 10 Apr 2006 08:42:35 +1000 Subject: [CRYPTO] digest: Add alignment handling Some hash modules load/store data words directly. The digest layer should pass properly aligned buffer to update()/final() method. This patch also add cra_alignmask to some hash modules.
