Store OTPs per user #6

Open eklem opened 2 years ago

Add a user level. Encrypt/decrypt per user. Not sure how to do this on near field communication.

Maybe like this:

Each user gets a unique user ID created when entering the page first time.
When two users connect the first time, create a communication key between the two connecting. Base it on the two IDs and randomness?

Or maybe the NFC has some unique ID that we should use to ID users.

One user combo ID and one message ID. The user combo ID doesn't need to be the same each time since both it and the message ID will be sent in clear text every time.

user combo ID meaning one ID for two peoples communication.

For the sender to choose the correct receiver (correct user combo ID), the keys needs to have a nick added to it.

Need a group name for the keys (to be stored in indexedDB). And then when dsitributing keys, how many in that group (minimum 2)

So when encrypting a message, you choose a group for your message, get an input box, add your message and get an encrypted version to share in a chat or Facebook, Twitter, email etc.
