  === Security Enhancements ===

-  * The `glibc` package in Fedora 8 had [http://people.redhat.com/drepper/sha-crypt.html support] for passwords using SHA256 and SHA512 hashing.  Before only DES and MD5 were available.  The tools have now been extended in Fedora 9. Password hashing using the SHA-256 and SHA-512 hash functions is now supported.

- To switch to SHA-256 or SHA-512 on an installed system, use `authconfig --passalgo=sha256 --update` or `authconfig --passalgo=sha512 --update`.  You can also configure the hashing method in a GUI using `authconfig-gtk`.  Existing user accounts won't be affected until their passwords are changed.
+ To switch to SHA-256 or SHA-512 on an installed system, use {{{authconfig --passalgo=sha256 --update}}} or {{{authconfig --passalgo=sha512 --update}}}.  Alternatively, use the {{{authconfig-gtk}}} GUI tool to configure the hashing method.  Existing user accounts will not be affected until their passwords are changed.
  
- SHA-512 is used by default on newly installed systems.  Other algorithms can be configured only for kickstart installations, by using the `--passalgo` or `--enablemd5` options of the kickstart command `auth`. If your installation does not use kickstart, use `authconfig` as described above, then change the `root` password and passwords of any other users created after installation.

+  * New values for the `crypt_style` option, and the new options `hash_rounds_min`, and `hash_rounds_max`, are now supported in the `[defaults]` section of `/etc/libuser.conf`. Refer to the `libuser.conf(5)` man page for details.
