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

Enable debugging.
    This option takes an integer number as its argument. The value of *[I-Font]number is constrained to being:
    in the range  0 through 9999

    Specifies the debug level.

    This option takes an integer number as its argument. The value of *[I-Font]number is constrained to being:

Pass the extended usage information through a pager.

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).

One of the following exit values will be returned:

Successful program execution.

The operation failed or the command syntax was not valid.
