Using the button

The key's push button can be used for two operations :

a short press : the stored password is typed. The status LED blinks.
a long press (5 seconds) : the stored password is deleted. The status LED turns off.

Caution : The key mimics an USB keyboard. This means that the password will be typed IN PLAIN TEXT, as if you were typing it.

The key can be controlled through a python script. Use python3 to execute it : python3 command.py [argument]

The following arguments can be passed :

-h : display a help message and exit.
-e <string> : echoes the string, i. e. the key types the string.
n <integer> : generates a new password of the length given by the integer.
r : read the password, i. e. the key types the string. This is equivalent to a short press on the key's button.
w <string> : write the password given by the string in the key's memory. Note that the string should be ASCII.
d : delete the password stored in the key's memory. This is equivalent to a long press on the key's button.
l <integer>: set the length of the password stored in the key's memory using the integer.
L <0|1> : switch on (1) or off (0) the status LED of the key.
H : echoes a short help, i. e. the key types an help
f <0|1> : adds (1) or not (0) a linefeed after the password. This can be useful to hit Enter after the password has been entered.
a <0|1> : automatically types (1) or not (0) the password at boot time, i. e. when the key is plugged. Default is 0.
