Dear Wiki user, You have subscribed to a wiki page or wiki category on "Fedora Project Wiki" for change notification. The following page has been changed by MurrayMcAllister: http://fedoraproject.org/wiki/Docs/Beats/Security?action=diff&rev2=44&rev1=43 The comment on the change is: editorial pass on new content added after f8 release... ------------------------------------------------------------------------------ === Security Enhancements === - * Fedora continues to improve its many proactive [http://fedoraproject.org/wiki/Security/Features security features]. + Fedora continues to improve its many proactive [http://fedoraproject.org/wiki/Security/Features security features]: - * 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. + * The `glibc` package in Fedora 8 had [http://people.redhat.com/drepper/sha-crypt.html support] for passwords using SHA256 and SHA512 hashing. Previously, 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. + SHA-512 is used by default on newly installed systems.

If your installation does not use kickstart, use `authconfig` as described above, and then change the `root` password, and passwords for other users created after installation. - New options were added to `libuser`, `pam` and `shadow-utils` to support these password hashing algorithms. `authconfig` configures all these options automatically, so it is usually not necessary to modify them manually. + New options were added to `libuser`, `pam`, and `shadow-utils`, to support these password hashing algorithms. Running {{{authconfig}}} configures all these options automatically, so it is not necessary to modify. + * 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. - * New values of the `crypt_style` option and new options `hash_rounds_min` and `hash_rounds_max` are now supported in the - `[defaults]` section of `/etc/libuser.conf`.

Refer `login.defs(5)` for more details. Corresponding options were added to `chpasswd(8)` and `newusers(8)`. + * New options `ENCRYPT_METHOD`, `SHA_CRYPT_MIN_ROUNDS`, and `SHA_CRYPT_MAX_ROUNDS`, are now supported in `/etc/login.defs`.
