of number is constrained to being:
in the range 0 through 9999

Specifies the debug level.

-s number, --keysize=number

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).
