I have a client that is wishing to build a peer to peer end-to-end encryption app.
They are in the first stages and looking for an experienced development team to partner with.
This will be an android based app that is able to be push to the phone through the imei. This needs to have extensive messaging and presence protocol (XMBB) with Sockets-based chat. It will be end-to-end encrypted, encoded on device and transferred to server (encrypted in transit), then transferred to final recipient. Only on end device is decoded. NOT held on server, or be able to be decoded at any process.
The app (and device once installed) will have open source encryption code open to independent review.
Double ratchet algorithm encryption protocol. CURVE25519, AES-256 and HMAC-SHA256 as primitives. (singal open source protocol)
4 sections with easy coding to do a 5th.
HOME, CHAT, VAULT, PROFILE
Remote installation (WiFi) via IMEI avail on android
Back end platform for resellers to see active subscribers/active users
Normal mode and Dark mode (themes) light and dark
Send photos within the app (vault and live photos/videos/notes)
Bubble messaging style (WhatsApp)
Able to send 'non-forwardable' msgs/photos/videos
Voice msgs, audio recording with voice changer (4 types)
Password access and fail safe
Self destruct msgs
The app needs to have full device control, authorization and permissions, being able to control updates and services.
Phone open to stormshield
Eventually the app will move from AndroidOS to PrivateOS, coding needs to be adapted to this when needed.
High end business people and government officials.
This is just a basic understanding of the direction of the company, there will be more features once the client commits to a solid and capable dev team.
My client needs a detailed direction plan and estimated quote on the development and any examples of similar projects you have done before and/or credited cryptologists you would use/recommend within development.
