*[B-Font]psktool [*[B-Font]-flags] [*[B-Font]-flag [*[I-Font]value]] [*[B-Font]--option-name[[=| ]*[I-Font]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

    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.

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 *[I-Font]number is constrained to being:
    in the range  0 through 512

Specify the username to use.

Specify a pre-shared key file.

    This option will specify the pre-shared key file to store the generated keys.

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 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:

Successful program execution.

The operation failed or the command syntax was not valid.
