    @gohan in other words, you use an old release ;)

    Do you feel secure today? No? Start requiring some signatures and feel better tomorrow ;)

      I can assure you I am using 2.2 from development as I am also running new driver. So unless you changed something in the last 3 weeks on the development branch it still works, unless the nodes are keeping the key saved.

        @gohan have you verified your communications are actually encrypted?

          @gohan If you see here, you will find that unless you use the simple password option, AES key is fetched from EEPROM: https://github.com/mysensors/MySensors/blob/28c4f3f19e7026f56fd9bbc61d566f770fd7a9d2/hal/transport/MyTransportRF24.cpp#L68
          So either you are using the simple flag, nothing at all, or not using the key you think you use.

              @gohan Perhaps on a rpi GW where there is no EEPROM, but I am talking about the nodes.

                Well, if I have communication working it means the node should be encrypting data. I'll have to try with clear eeprom and try flashing sketch again

                  @gohan not if there is no encryption at all. You could try to use simple password option on a node with various passwords and see if it is detected by your gw at all.

                    @anticimex I guess you were right... the gw and node aren't using the AES key. So where am I supposed to add it in the gateway?

                      @gohan you set that with the configure arguments I suspect, but I can't see it in the documentation. @marceloaqno perhaps knows how the rPi port handles this. I'm on a phone so I can't check the code easily. But you should be able to find it in the transport driver for rPi. On the rPi it can probably be defined in the code as it does not have a personalizer.

                        @anticimex It doesn't read it from the mysonfig.h for sure as it is where I always put it

                          @gohan MyConfig.h does to my knowledge not have a define value for that. You cannot add new definitions to it and expect them to have an effect. If there is one already defined in there, as a comment or not, and it does not have an effect, please report a bug on it.

                            @marceloaqno Thank's for you help. I have other question.. general I try configure my gateway to work with security & signing, but they doesn't work. Where is problem? On the bottom i send point what it do it:

                            Gateway:

                            1. ./configure --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mygateway1 --my-mqtt-password=PASS --my-mqtt-user=USER --my-rf24-encryption-enabled --my-signing=software --my-signing-request-signatures --my-signing-request-gw-signatures-from-all
                            2. make
                            3. sudo make install
                            4. sudo systemctl enable mysgw.service
                            5. sudo systemctl start mysgw.service
                            6. sudo mysgw --gen-soft-hmac-key
                            7. sudo mysgw --set-soft-hmac-key=02417628BC1573CC380...
                            8. sudo mysgw --gen-soft-serial-key
                            9. sudo mysgw --set-soft-serial-key=00762CD152B868F7EB
                            10. sudo mysgw --gen-aes-key
                            11. sudo mysgw --set-aes-key= A790AD78B2D8B4DBBB5B2C4B9DD6DAF3

                            Node:

                            1. Load script SecurityPersonalizer.ino
                            2. Uncomment and send sketch to arduino
                            #define USE_SOFT_SIGNING
                            #define STORE_SOFT_KEY

                            #define STORE_AES_KEY
                            #define USER_AES_KEY
                            
                            #define MY_SOFT_HMAC_KEY 0X2,0X41,0X76,0X28,0XBC,0X15,0X73,0XCC,0X38...

                            1. Read all value from EPROM (test save):
                            Personalization sketch for MySensors usage.
                            -------------------------------------------
                            EEPROM configuration:
                            SOFT_HMAC_KEY | 02417628BC1573CC380DE0FADF7C87D7D3C77272A783E6E438786A07C3A8C6CF

                            --------------------------------
                            Personalization is now complete.
                            
                            1. Send sample sketch to arduino:

                            I followed all the step that you mentioned in your post to establish the serial gateway. However I am still not able to receive the message from arduino. Could you please what to do?

                            import RPi.GPIO as GPIO
                            from lib_nrf24 import NRF24
                            import time
                            import spidev

                            GPIO.setmode(GPIO.BCM)

                            pipes = [[0xE8, 0xE8, 0xF0, 0xF0, 0xE1], [0xF0, 0xF0, 0xF0, 0xF0, 0xE1]]
                            radio = NRF24(GPIO, spidev.SpiDev())

                            radio.begin(0,8)

                            radio.setPayloadSize(32)
                            radio.setChannel(0x76)
                            radio.setDataRate(NRF24.BR_1MBPS)
                            radio.setPALevel (NRF24.PA_MAX)
                            radio.setAutoAck(True)
                            radio.enableDynamicPayloads()
                            radio.enableAckPayload()
                            radio.openReadingPipe(1 ,pipes[1])
                            radio.printDetails()
                            radio.startListening()
                            radio.GPIO.cleanup()

                            Please find below my raspberry code..can you please suggest , if there is any issue with code or am I missing anything ?

                              @rajeev2301 please don't split our effort to help you into multiple threads. It wastes people's time when some information is in one thread and some in another thread.

                                To upgrade to the latest release, can I use git pull, or is it better to delete the directory and start again?

                                  @wes you can pull. Just as long as you verify that your working directory is clean or only contains changes you intend to have. And you have the appropriate branch or tag checked out.

                                  Do you feel secure today? No? Start requiring some signatures and feel better tomorrow ;)

                                    @marceloaqno Thank's for you help. I have other question.. general I try configure my gateway to work with security & signing, but they doesn't work. Where is problem? On the bottom i send point what it do it:

                                    Gateway:

                                    1. ./configure --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mygateway1 --my-mqtt-password=PASS --my-mqtt-user=USER --my-rf24-encryption-enabled --my-signing=software --my-signing-request-signatures --my-signing-request-gw-signatures-from-all
                                    2. make
                                    3. sudo make install
                                    4. sudo systemctl enable mysgw.service
                                    5. sudo systemctl start mysgw.service
                                    6. sudo mysgw --gen-soft-hmac-key
                                    7. sudo mysgw --set-soft-hmac-key=02417628BC1573CC380...
                                    8. sudo mysgw --gen-soft-serial-key

                                      @pepson signing is radio agnostic. It has nothing to do with the radio.

                                      Do you feel secure today? No? Start requiring some signatures and feel better tomorrow ;)

                                        @wes you can pull. Just as long as you verify that your working directory is clean or only contains changes you intend to have. And you have the appropriate branch or tag checked out.

                                        @anticimex @wes Can I please ask how to update? I mean, the right command to type.
                                        I have the folder "MySensors" on documents of my user in Pi:

                                        /home/sineverba/MySensors

                                        Of course I have all installed and perfectly working now (I'm on the 2.2.0 rc2).

                                        I need also to relaunch the ./config command?

                                        Thank you to both and all!
