     kstash - store the KDC master password in a file


     kstash [-e string | --enctype=string] [-k file | --key-file=file]
            [--convert-file] [--random-key] [--master-key-fd=fd]
            [--random-key] [-h | --help] [--version]


     kstash reads the Kerberos master key and stores it in a file that will be
     used by the KDC.

     Supported options:

     -e string, --enctype=string
             the encryption type to use, defaults to DES3-CBC-SHA1.

     -k file, --key-file=file
             the name of the master key file.

             don’t ask for a new master key, just read an old master key file,
             and write it back in the new keyfile format.

             generate a random master key.

             filedescriptor to read passphrase from, if not specified the
             passphrase will be read from the terminal.


     /var/heimdal/m-key is the default keyfile if no other keyfile is
     specified.  The format of a Heimdal master key is the same as a keytab,
     so ktutil list can be used to list the content of the file.
