KSTASH(8) System Manager's Manual KSTASH(8)

kstashstore 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:

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