From 9ec1d35f29c5d3c0c6a2461610c7db494a0d9aa9 Mon Sep 17 00:00:00 2001 From: Richard Levitte Date: Wed, 12 Feb 2003 17:20:39 +0000 Subject: [PATCH] Adjust DES_cbc_cksum() so the returned value is the same as MIT's mit_des_cbc_cksum(). The difference was first observed, then verified by looking at the MIT source. --- CHANGES | 6 ++++++ crypto/des/cbc_cksm.c | 9 +++++++++ 2 files changed, 15 insertions(+) diff --git a/CHANGES b/CHANGES index cde8cca58b..08c0124893 100644 --- a/CHANGES +++ b/CHANGES @@ -420,6 +420,12 @@ TODO: bug: pad x with leading zeros if necessary Changes between 0.9.7 and 0.9.7a [XX xxx 2003] + *) Adjust DES_cbc_cksum() so it returns the same value as the MIT + Kerberos function mit_des_cbc_cksum().
