psktool [-flags] [-flag [value]] [--option-name[[=| ]value]]
All arguments must be options.
Program that generates random keys for use with TLS-PSK. The keys
are stored in hexadecimal format in a key file.

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.

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