DES transition
==============

The Data Encryption Standard (DES) is widely recognized as weak.  The
krb5-1.7 release contains measures to encourage sites to migrate away
- From using single-DES cryptosystems.  Among these is a configuration
variable that enables "weak" enctypes, which defaults to "false"
beginning with krb5-1.8.
