DES transition
==============
The Data Encryption Standard (DES) is widely recognized as weak. The
krb5-1.7 release will contain measures to encourage sites to migrate
away from using single-DES cryptosystems. Among these is a
configuration variable that enables "weak" enctypes, but will default
to "false" in the future. Additional migration aids are planned for
future releases.
