From e9cc33d6f2b7f35c6f5e349fd83fb9ae0bc66226 Mon Sep 17 00:00:00 2001 From: Gary Lin Date: Mon, 10 Apr 2017 17:23:29 +0800 Subject: Cryptlib: remove DES Disable DES completely since it's already old and insecure. This makes MokManager not support the DES based password hash but probably no one is using it.
