From 357fb60502ede168fa1b76b996298e0045e24b59 Mon Sep 17 00:00:00 2001 From: Horia Geanta Date: Tue, 3 Jul 2012 19:16:53 +0300 Subject: [PATCH] crypto: talitos - add sha224, sha384 and sha512 to existing AEAD algorithms With this, now all combinations of CBC: AES, 3DES-EDE with HMAC: SHA-1, SHA-224, SHA-256, SHA-384, SHA-512 are supported.
