From 43600106e32809a4dead79fec67a63e9860e3d5d Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 16 May 2006 22:06:54 +1000 Subject: [CRYPTO] digest: Remove unnecessary zeroing during init Various digest algorithms operate one block at a time and therefore keep a temporary buffer of partial blocks. This buffer does not need to be initialised since there is a counter which indicates what is and isn't valid in it.
