psktool — GnuTLS PSK tool
psktool [ −flag [value] ...] [ −−opt−name [[=|]value] ...]
Program that generates random keys for use with TLS-PSK. The keys are stored in hexadecimal format in a key file.
−d
number,
−−debug=numberEnable 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=numberspecify 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=stringspecify a username.
−p
string,
−−passwd=stringspecify a password file.
−h,
−−helpDisplay usage information and exit.
−!,
−−more−helpPass 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.
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).
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
