I'd like to allow customers to submit orders for custom playing cards with both sides printed on. Are there any services that provide an API for this since I don't have printers?
I'm using cryptomator for file encryption right now. I'd like to use a small, portable, C-based (for familiarity and guaranteed future support), open source, command-line/terminal program to encrypt txt files so I can read it and potentially make fixes if it ever stops being supported. What should I use?
