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.
