Name

psktool — GnuTLS PSK tool

Synopsis

psktool [ −flag [value] ...] [ −−opt−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

−d number, −−debug=number

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. 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 a username.

−p string, −−passwd=string

specify a password file..

−h, −−help

Display usage information and exit.

−!, −−more−help

Pass the extended usage information through a pager.

−v [{v|c|n}], −−version[={v|c|n}]

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).

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.

70 (EX_SOFTWARE)

libopts had an internal operational error. Please report it to autogen-users@lists.sourceforge.net. Thank you.
