25
26       -s num, --keysize=num
27              Specify the key size in bytes (default is 32-bytes or 256-bits).

EXAMPLES

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