OpenWebNet password

OpenWebNet password
You are encouraged to solve this task according to the task description, using any language you may know.

Calculate the password requested by ethernet gateways from the Legrand / Bticino MyHome OpenWebNet home automation system when the user's ip address is not in the gateway's whitelist

Note: Factory default password is '12345'. Changing it is highly recommended !

conversation goes as follows

← *#*1##
→ *99*0##
← *#603356072##

at which point a password should be sent back, calculated from the "password open" that is set in the gateway, and the nonce that was just sent

→ *#25280520##
← *#*1##
