.SH "DESCRIPTION"
Program  that generates random keys for use with TLS-PSK. The
keys are stored in hexadecimal format in a key file.
.SH "OPTIONS"
.TP
.NOP \f\*[B-Font]\-d\f[] \f\*[I-Font]number\f[], \f\*[B-Font]\-\-debug\f[]=\f\*[I-Font]number\f[]
Enable debugging.
This option takes an integer number as its argument.
The value of
\f\*[I-Font]number\f[]
is constrained to being:
.in +4
.nf
.na
in the range  0 through 9999
.fi
.in -4
.sp
Specifies the debug level.
.TP
.NOP \f\*[B-Font]\-s\f[] \f\*[I-Font]number\f[], \f\*[B-Font]\-\-keysize\f[]=\f\*[I-Font]number\f[]
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
\f\*[I-Font]number\f[]
is constrained to being:
.in +4
.nf
.na
in the range  0 through 512
.fi
.in -4
.sp
.TP
.NOP \f\*[B-Font]\-u\f[] \f\*[I-Font]string\f[], \f\*[B-Font]\-\-username\f[]=\f\*[I-Font]string\f[]
Specify the username to use.
.sp
.TP
.NOP \f\*[B-Font]\-p\f[] \f\*[I-Font]string\f[], \f\*[B-Font]\-\-pskfile\f[]=\f\*[I-Font]string\f[]
Specify a pre-shared key file.
.sp
This option will specify the pre-shared key file to store the generated keys.
.TP
.NOP \f\*[B-Font]\-\-passwd\f[]
This is an alias for the \fI--pskfile\fR option.
.sp
.B
NOTE: THIS OPTION IS DEPRECATED
.TP
.NOP \f\*[B-Font]\-h\f[], \f\*[B-Font]\-\-help\f[]
Display usage information and exit.
.TP
.NOP \f\*[B-Font]\-\&!\f[], \f\*[B-Font]\-\-more-help\f[]
Pass the extended usage information through a pager.
.TP
.NOP \f\*[B-Font]\-v\f[] [{\f\*[I-Font]v|c|n\f[] \f\*[B-Font]\-\-version\f[] [{\f\*[I-Font]v|c|n\f[]}]}]
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.

.SH EXAMPLES
To add a user 'psk_identity' in \fIkeys.psk\fP for use with GnuTLS run:
.br
.in +4
.nf
$ ./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
$
.in -4
.fi
.sp
This command will create \fIkeys.psk\fP if it does not exist
and will add user 'psk_identity'.
.SH "EXIT STATUS"
One of the following exit values will be returned:
.TP
.NOP 0 " (EXIT_SUCCESS)"
Successful program execution.
.TP
.NOP 1 " (EXIT_FAILURE)"
The operation failed or the command syntax was not valid.
.TP
.NOP 70 " (EX_SOFTWARE)"
libopts had an internal operational error.  Please report
