How to connect a ZKTeco device with laravel which is protected by Communication Password

Question

I am facing an issue that my client have an attendance device ZKTeco K50 which is protected by communication password. Using rats/zkteco when I send request for connecting with device it connects but after that I am unable to get data from device and send data to device due to communication password protection.

I checked in package but there is no way to send communication password and also tried to alter the package but it did nothing.

Please answer if anyone know anything.

Answer 1

@KGG is correct. I will offer a few hints to get you started:

1. this is the best description of the ZKTeco protocol that I have found: https://github.com/adrobinoga/zk-protocol . Reading it is a good idea.

2. you will want to research the CMD_CONNECT message. When sending it gets a CMD_ACK_UNAUTH message in response, you need to fetch the comm key and compute the crazy ZKTeco secret

3. You send a CMD_AUTH message to the clock inserting the magical number computed in point 2. If it is good you will get a CMD_ACK_OK message

4. you will find a python library from the author of the protocol spec here: https://github.com/adrobinoga/pyzatt that looks pretty good to my eyes though I don't do python

5. And here https://github.com/fananimi/pyzk you will find the function make_comm_key which should get you started

You have to check if your server provider gives you access to the Firewall in my case I manage WHM where I configure IP and port
