From 5af46547ec451918f3ba51efe59b317d33adf701 Mon Sep 17 00:00:00 2001 From: Kevin Coffman Date: Wed, 17 Mar 2010 13:03:05 -0400 Subject: gss_krb5: Use confounder length in wrap code All encryption types use a confounder at the beginning of the wrap token. In all encryption types except arcfour-hmac, the confounder is the same as the blocksize. arcfour-hmac has a blocksize of one, but uses an eight byte confounder. Add an entry to the crypto framework definitions for the confounder length and change the wrap/unwrap code to use the confounder length rather than assuming it is always the blocksize.
