Synopsis

psktool [-flags] [-flag [value]] [--option-name[[=| ]value]]

Description

Program  that generates random keys for use with TLS-PSK. The keys are stored in hexadecimal format in a key file.

Options

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.

-p string, --pskfile=string

Specify a pre-shared key file.

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'.

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.
