Hello, I'm Abhishek, an undergraduate student actively seeking job opportunities while immersing myself in the world of embedded systems. I have two years of experience as an intern, working with AVR/Arduino, STM32, and ESP series microcontrollers, as well as PCB designing using KiCAD. Additionally, I've gained experience with Pixhawk and DJI-based drones. Currently, I'm focused on expanding my knowledge and skills in this exciting field. Excited to connect and learn within the DevHeads community!

Hi,

I am looking into whether I can encrypt a python script so the code is obfuscated. it should decrypt it when the script runs.
I have seen few packages to do this, like:
https://github.com/Falldog/pyconcrete
https://juanlao7.github.io/codeclose/documentation
https://changsin.medium.com/how-to-protect-python-source-code-5892a153d0ac
https://pypi.org/project/sourcedefender/

I was wondering what your thoughts are on this and suggestion for a approach you would take?

Why 10-bit I2C Slave Addressing is not widely used in device libraries and example codes? Even, I often use a 7-bit slave address. It seems to me that either 10-bit addressing is only for special cases or it's a bit of a challenge to implement in code. Appreciate any perspective, experience @abhishek awasthi @Navadeep @ShreeshaN @Aditya thakekar

Ttechielew By “when the code runs” do you mean encrypt the binary?

brotherjoons•1/18/24, 6:11 AM

Hi @techielew , encrypt the .py source code or .pyc compiled code and decrypt them on the fly so the Python interpreter could run it.
I was curious about the best practices in doing so. Thanks

ShreeshaN•1/18/24, 6:14 AM

My guess is that use of 8-bit or 10-bit slave address will add a byte more in every communication packet of data and considering slow speed of I2C, devices using 8-bit or 10-bit are not popular and adding extra implementation of addressing will increase I2C device library for small microcontrollers.

Umesh Lokhande•1/18/24, 6:31 AM

I agree though. Not sure who will love this 10-bit addressing and implementation. I wonder even for MPU users are there enough bus drivers support for 10-bit I2C addresses in user space packages

techielew•1/18/24, 6:42 AM

Is this for a commercial project? How imperative is it that either the source or the binary are encrypted? What are you concerned about protecting against? IP theft/cloning? Vulnerabilities? Something else?

There are commercial products like IAR Embedded Trust that provide application encryption and other security measures. And other services that encrypt binaries. Of course, those aren't FOSS..

Aditya thakekar•1/18/24, 6:56 AM

Most mcu work on the assumption that slave disables itself on not receiving matching address. 10 bit is used in STM32 series but not all support. NACK is disabled function.

Navadeep•1/18/24, 7:26 AM

Makes sense. As well, 10-bit one can address upto (2^10)-1 devices. But come on, I haven't seen anyone using even 127 device itself on a single bus.

Navadeep•1/18/24, 7:28 AM

Curious: What was your highest? I've used 8 of them multiplexed with the same address and 8 such ones in a single bus. In SPI though I've seen designs having 64 subordinate nodes.

Aditya thakekar•1/18/24, 7:30 AM

Yes that's another... Haven't seen that high of a bus load either
