psktool — GnuTLS PSK tool

Synopsis

psktool [-flags] [-flag [value]] [--option-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.
