psktool(1)                      User Commands                     psktool(1)

NAME         top

       psktool - GnuTLS PSK tool

SYNOPSIS         top

       psktool [-flags] [-flag [value]] [--option-name[[=| ]value]]

       All arguments must be options.

DESCRIPTION         top

       Program  that generates random keys for use with TLS-PSK. The keys
       are stored in hexadecimal format in a key file.

OPTIONS         top

       -d number, --debug=number
              Enable debugging.  This option takes an integer number as its
              argument.  The value of number is constrained to being:
                  in the range  0 through 9999

              Specifies the debug level.

       -s number, --keysize=number
              Specify the key size in bytes (default is 32-bytes or
              256-bits).  This option takes an integer number as its
              argument.  The value of number is constrained to being:
                  in the range  0 through 512

       -u string, --username=string
              Specify the username to use.

       -p string, --pskfile=string
              Specify a pre-shared key file.

              This option will specify the pre-shared key file to store the
              generated keys.

       --passwd
              This is an alias for the --pskfile option.

              NOTE: THIS OPTION IS DEPRECATED

       -h, --help
              Display usage information and exit.

       -!, --more-help
              Pass the extended usage information through a pager.

       -v [{v|c|n --version [{v|c|n}]}]
              Output version of program and exit.  The default mode is `v',
              a simple version.  The `c' mode will print copyright
              information and `n' will print the full copyright notice.

EXAMPLES         top

       To add a user 'psk_identity' in keys.psk for use with GnuTLS run:
           $ ./psktool -u psk_identity -p keys.psk
           Generating a random key for user 'psk_identity'
           Key stored to keys.psk
           $ cat keys.psk
           psk_identity:88f3824b3e5659f52d00e959bacab954b6540344
           $

       This command will create keys.psk if it does not exist and will add
       user 'psk_identity'.

EXIT STATUS         top

       One of the following exit values will be returned:

       0  (EXIT_SUCCESS)
              Successful program execution.

       1  (EXIT_FAILURE)
              The operation failed or the command syntax was not valid.

       70  (EX_SOFTWARE)
              libopts had an internal operational error.  Please report it
              to autogen-users@lists.sourceforge.net.  Thank you.
