I’ve built an iOS app in bubble (it’s been accepted and is live in case anyone wants confirmation that it’s possible). It’s a journaling app and I want to encrypt the text of the journal entries from users. I’ve tried the AES256 encrypt & decrypt plug-in and it works how I want except for there is just a single encryption key that I set. So I am able to decrypt any entries as I want, which isn’t what users might expect if I advertise that it’s end to end encrypted. I want to be able to define a private encryption key per user. Any suggestions on how I might set this up?
