### Creating and Destroying a Kerberos Database

If you need to create a new Kerberos database, use the `kdb5_util` `create` command. The syntax is:

         kdb5_util create [-s]

If you specify the `-s` option, `kdb5_util` will stash a copy of the master key in a stash file. (See Creating a Stash File.) For example:

         shell% /usr/local/sbin/kdb5_util -r ATHENA.MIT.EDU create -s
         kdb5_util: No such file or directory while setting active database to
         => '/usr/local/var/krb5kdc/principal'
         Initializing database '/usr/local/var/krb5kdc/principal' for
         => realm 'ATHENA.MIT.EDU',
         master key name 'K/M@ATHENA.MIT.EDU'
         You will be prompted for the database Master Password.
         It is important that you NOT FORGET this password.
         Enter KDC database master key:  <= Type the master password.
         Re-enter KDC database master key to verify:  <= Type it again.
         shell%

If you need to destroy the current Kerberos database, use the `kdb5_util` `destroy` command. The syntax is:

         kdb5_util destroy [-f]

The `destroy` command destroys the database, first overwriting the disk sectors and then unlinking the files. If you specify the `-f` option, `kdb5_util` will not prompt you for a confirmation before destroying the database.

         shell% /usr/local/sbin/kdb5_util -r ATHENA.MIT.EDU destroy
         kdb5_util: Deleting KDC database stored in /usr/local/var/krb5kdc/principal, are you sure
         (type yes to confirm)? <== yes
         OK, deleting database '/usr/local/var/krb5kdc/principal'...

         shell%
