Raspberry Gateway 2.1.1 + signing

[Anticimex]

@t3chie could you please include the startup messages from the gateway? Looks like it still does not initialize properly. It should not have a problem generating nonces if it thinks personalization is OK.

I am on Skype with the same Nick if you want more synchronous communication.

@t3chie hm, odd. And you get the validation message twice. I must have messed something up. I'll have a closer look tonight and get back to you. Thanks for helping out!

[Anticimex]

@t3chie I believe I found the issue on my pr. Sloppy coding is all I can say... I will notify you once I have resolved it. In the meantime you can delete your copy of my branch (I tend to force push to my pull requests).

git checkout development
git branch -D fallberg-signing

[Anticimex]

@t3chie I've pushed updates now. It should resolve the problems. I accidentally excluded the part where the backends are initialized, and there are safeguards against that so it refused to calculate nonces for signing. You should now get a "SGN:INI:BND OK" after "SGN:PER:OK"

[t3chie]

@Anticimex I have checked out the signing branch and recompiled:

[Anticimex]

@t3chie looks good to me. I cannot see any errors at least :)

[t3chie]

@Anticimex Thanks for your help!

[MasMat]

Hi guys,
I read this thread because it was the only the search found ("raspberry signing").
I'm building a gw (the plan is raspberry 3, rf24). Since it's in a populated area, I want signing (my other project is remote, so no real worries there).
I'm trying to figure out the configuration part for the Raspberry and some of the options:
-software signing AND rf24 encryption. Two different things, right? I thought I would just use signing if that's adequate.
-does master branch work or must I use dev? What's the difference in everyday use?
-I think pin 7 is usefully located (pro mini) and A5 and A6 less convinient, can I use those for the signing?

Also, is there a guide or a thread for a noob regarding setting this up? If not, should we start a new thread?

Thanks guys. I like the info here.

[Anticimex]

@MasMat hi, well, ./configure --help should give you a list of configuration options.
To my knowledge signing on rPi uses no pins as it is software based and uses the Linux random number generator. So Arduino specific pins make no sense on a rPi.
For Arduino configurations and signing and encryption in general, there is a signing thread on this forum and the first post of that thread links to doxygen documentation that describe the exact details for both the official MySensors version and the beta version.
See https://forum.mysensors.org/topic/1021/security-introducing-signing-support-to-mysensors

[MasMat]

@Anticimex Whew! Not a light read that thread. Esp for someone noobish like me. Also it has a lot to do with ATSHA and I was thinking I'd do just software signing.

The pin idea was for the config - to be used for other nodes. Not gw.

The quick questions: do I have to use dev branch?
This way I'll be able to get going and see what roadblocks I hit.

[Anticimex]

@MasMat a generic pin config for the nodes depend on whether you use identical nodes, as the pin assignment is hw specific.

Regarding signing on rPi, try searching the forum. It has been discussed before, and I don't use rPi myself so I don't remember the exact flags, nor do I remember if the full support for signing on rPi made it into the latest release.
I know a new release is about to come though.

[MasMat]

Thanks. I'll keep looking then.
Most likely my nodes will be almost alike, so that's why I'd rather choose a pin that I hardly ever would use (as opposed to default pin 7).
