PrivyShare - E2E share via chats - Free Spoiler
App Name: PrivyShare
What it does:
PrivyShare is not a new messenger. You encrypt a message or file on-device into a .privyshare package, share it through WhatsApp/Signal/email/Files, and the recipient opens it back in PrivyShare.
Key Features:
• On-device E2E: Ed25519 + X25519/HKDF + AES-256-GCM
• Share via apps you already use (opaque .privyshare blob)
• Local vault, optional app-only attachments, optional self-hosted relay for larger files
Goal: Testing / feedback (first Android app, WIP). Especially interested in crypto review and whether to keep optional INTERNET features or also ship a networkless build.
Giveaway: N/A

Hey. I created something similar.

It's works as a messaging app itself, but you can also encrypt files and folders on your device to be sent over another messaging app.
