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.

Code quality:

* Fix MITKRB5-SA-2011-006 and MITKRB5-SA-2011-007 KDC denial of
  service vulnerabilities [CVE-2011-1527 CVE-2011-1528 CVE-2011-1529
  CVE-2011-1530].

* Update the Fortuna implementation to more accurately implement the
  description in _Cryptography Engineering_, and make it the default
  PRNG.

* Add an alternative PRNG that relies on the OS native PRNG.

Developer experience:

* Add the ability for GSSAPI servers to use any keytab key for a
  specified service, if the server specifies a host-based name with no
  hostname component.

* In the build system, identify the source files needed for
  per-message processing within a kernel and ensure that they remain
  independent.

* Allow rd_safe and rd_priv to ignore the remote address.

* Rework KDC and kadmind networking code to use an event loop
  architecture.

* Add a plugin interface for providing configuration information.

Administrator experience:

* Add more complete support for renaming principals.

* Add the profile variable ignore_acceptor_hostname in libdefaults. If
  set, GSSAPI will ignore the hostname component of acceptor names
  supplied by the server, allowing any keytab key matching the service
  to be used.

* Add support for string attributes on principal entries.

* Allow password changes to work over NATs.

End-user experience:

* Add the DIR credential cache type, which can hold a collection of
  credential caches.

* Enhance kinit, klist, and kdestroy to support credential cache
  collections if the cache type supports it.

* Add the kswitch command, which changes the selected default cache
  within a collection.

* Add heuristic support for choosing client credentials based on the
  service realm.

* Add support for $HOME/.k5identity, which allows credential choice
  based on configured rules.

* Add support for localization. (No translations are provided in this
  release, but the infrastructure is present for redistributors to
  supply them.)

Protocol evolution:

* Make PKINIT work with FAST in the client library.
