Is production mode needed for encrypted FS?

Hello. I have successfully encrypted root filesystem on Raspberry Pi with Zymkey in development mode. My goal is to prevent stealing the source code from SD card if the Raspberry gets stolen. So, I wonder, do I need to go into production mode or that’s not necessary, given that SSH is protected, USB and LAN deactivated? In other words, can encryption key be extracted from Zymkey in development mode in order to decrypt my SD? Thank you!

@chirikov - There is a table on our docs server that explains the differences between Developer and Production Mode. Binding, Device ID, and Authentication |
