23
24              Specifies the debug level.
25
26       -s number, --keysize=number
27              Specify the key size in bytes (default is 32-bytes or 256-bits).
28              This option takes an integer number as its argument.  The value
29              of number is constrained to being:
30                  in the range  0 through 512

EXAMPLES

60       To add a user 'psk_identity' in keys.psk for use with GnuTLS run:
61           $ ./psktool -u psk_identity -p keys.psk
62           Generating a random key for user 'psk_identity'
63           Key stored to keys.psk
64           $ cat keys.psk
65           psk_identity:88f3824b3e5659f52d00e959bacab954b6540344
66           $
67
68       This command will create keys.psk if it does not exist and will add
69       user 'psk_identity'.
