NAME

psktool − GnuTLS PSK tool

SYNOPSIS

psktool [−flags] [−flag [value]] [−−option-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 num, −−debug=num

Enable debugging. This option takes an integer number as its argument. The value of num is constrained to being:

in the range 0 through 9999

Specifies the debug level.

−s num, −−keysize=num

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 num is constrained to being:

in the range 0 through 512

−u str, −−username=str

Specify the username to use.

−p str, −−pskfile=str

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

−v arg, −−version=arg

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.

−h, −−help

Display usage information and exit.

−!, −−more−help

Pass the extended usage information through a pager.

EXAMPLES

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’.

One of the following exit values will be returned:
0 (EXIT_SUCCESS)

Successful program execution.

1 (EXIT_FAILURE)
