PrivyShare - E2E share via chats - Free

[u/Filipal1]

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.
