From 560c06ae1ab7c677002ea3b6ac83521bf12ee07d Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sun, 13 Aug 2006 14:16:39 +1000 Subject: [CRYPTO] api: Get rid of flags argument to setkey Now that the tfm is passed directly to setkey instead of the ctx, we no longer need to pass the &tfm->crt_flags pointer. This patch also gets rid of a few unnecessary checks on the key length for ciphers as the cipher layer guarantees that the key length is within the bounds specified by the algorithm. Rather than testing dia_setkey every time, this patch does it only once during crypto_alloc_tfm. The redundant check from crypto_digest_setkey is also removed.
