From 5311f248b7764ba8b59e6d477355f766e5609686 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 17 Dec 2007 21:34:32 +0800 Subject: [CRYPTO] ctr: Refactor into ctr and rfc3686 As discussed previously, this patch moves the basic CTR functionality into a chainable algorithm called ctr. The IPsec-specific variant of it is now placed on top with the name rfc3686. So ctr(aes) gives a chainable cipher with IV size 16 while the IPsec variant will be called rfc3686(ctr(aes)). This patch also adjusts gcm accordingly.
