From db131ef9084110d9e82549c0a627e157e8bb99d7 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 21 Sep 2006 11:44:08 +1000 Subject: [CRYPTO] cipher: Added block ciphers for CBC/ECB This patch adds two block cipher algorithms, CBC and ECB. These are implemented as templates on top of existing single-block cipher algorithms. They invoke the single-block cipher through the new encrypt_one/decrypt_one interface. This also optimises the in-place encryption and decryption to remove the cost of an IV copy each round.
