psktool(1)

NAME
psktool - GnuTLS PSK tool

SYNOPSIS
psktool [-flag [value]]... [--opt-name[[=| ]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

-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.
