NAME
       psktool - GnuTLS PSK tool

SYNOPSIS
       psktool [-flag [value]]... [--opt-name[[=| ]value]]...

       All arguments must be options.

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

OPTIONS
       -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.  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 a username.

       -p string, --passwd=string
	      specify a password file..

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

       This command will create passwd.psk if it does not exist and will add user 'psk_identity' (you will also be prompted for a password).

EXIT STATUS
       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.
