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.
--master-key-fd= 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.
