Secure code (from development stage to production stage)

[d-solis-tovar]

Hi,

I developed some Micropython code for my esp32 project. Once developed and before commercial launch, I would like to find ways to secure this code (preventing users access). As I understand, the options available are:

• Convert .py files to .mpy. Users can access the file system but they would need to decompile the files to be able to read the content
• Convert .py files to .mpy and disable REPL
• Build my own Micropython firmware

I don't know if there are any additional options. I would like to know which approach you recommend me.

Thanks in advance!
