From 0a270321dbf948963aeb0e8382fe17d2c2eb3771 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Fri, 30 Nov 2007 21:38:37 +1100 Subject: [CRYPTO] seqiv: Add Sequence Number IV Generator This generator generates an IV based on a sequence number by xoring it with a salt. This algorithm is mainly useful for CTR and similar modes. This patch also sets it as the default IV generator for ctr.
