RFID Raspberry Card Manager

RFID Raspberry Pi Card Manager written in Python with MVC and MQTT patterns

• ✅ Client server publish/subscribe messaging pattern (by using MQTT 3.1.1 protocol)
  
• ✅ Security and authentication (By using SSL and uthentication mechanism)
• ✅ MVC (Model-View-Controller)

How to use it

1. Install required packages (MQTT)
   

pip install -r requirements.txt --user

2. Generate certificates and keys:
   Generate pair of keys:
   openssl genrsa -des3 -out ca.key 2048
   Make certificate:
   openssl req -new -x509 -days 1826 -key ca.key -out ca.crt
   Make another pair of keys:
   openssl genrsa -out server.key 2048
   Sign certificate:
   openssl req -new -out server.csr -key server.key
   Verify certificate
   openssl x509 -req -in server.csr -CA ca.crt -CAkey ca.key -CAcreateserial -out server.crt -days 360
   

3. Make password file (in your mosquitto installation folder, e.g. /etc/mosquitto/):
   mosquitto_passwd -c passwd.conf server

4. Modify mosquitto.conf file. Append this lines to it:

   allow_anonymous false
   password_file //path to passwd.conf which you had made in section 3//
   port 8883
   cafile //path to ca.crt which you had made in section 2//
   certfile //path to server.crt which you had made in section 2//
   keyfile //path to server.key which you had made in section 2//

5. Navigate to client and server directory

6. Run script:

python3 main.py
