From 3952f17ed63434cc2154c3765ff97e1d4adab042 Mon Sep 17 00:00:00 2001 From: Lee Nipper Date: Thu, 10 Jul 2008 18:29:18 +0800 Subject: [PATCH] crypto: talitos - Add support for sha256 and md5 variants This patch adds support for: authenc(hmac(sha256),cbc(aes)), authenc(hmac(sha256),cbc(des3_ede)), authenc(hmac(md5),cbc(aes)), authenc(hmac(md5),cbc(des3_ede)). Some constant usage was changed to use aes, des, and sha include files.
