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’.

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.
