I've started on the code to generate the barcodes: https://github.com/verxcodes/codegen
It's totally just a start, but I wanted to get it out so everyone could check it out and provide input, etc. Please take a careful look at the ECDSA encryption and whether or not I'm doing it right... Comments, criticisms, edits, and pull requests welcome! I envision three repos - codegen, website, server - or something like that. What does everyone think? I totally agree we should get input from the manufacturers, but I don't want to stop work before hearing from them as I think that will be a long time coming... Part of this will be convincing them to change anyway. Cheers and Happy New Year!
