psktool − GnuTLS PSK tool
psktool [−flags] [−flag [value]] [−−option-name[[=| ]value]]
All arguments must be options.
Program that generates random keys for use with TLS-PSK. The keys are stored in hexadecimal format in a key file.
−d
num, −−debug=num Enable
debugging. This option takes an integer
number as its argument. The value of num is
constrained to being:
in the range 0 through 9999
Specifies the debug level.
−s
num, −−keysize=num 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 num is constrained to
being:
in the range 0 through 512
−u str, −−username=str Specify the username to use.
−p str, −−pskfile=str Specify a pre-shared key file.
This option will
specify the pre−shared key file to store the generated
keys.
−−passwd This is an alias for the --pskfile option.
NOTE: THIS
OPTION IS DEPRECATED
−v arg,
−−version=arg 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.
−h, −−help Display usage information and exit.
−!, −−more−help Pass the extended usage information through a pager.
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.
gnutls−cli−debug (1), gnutls−serv (1), srptool (1), certtool (1)
