Hello, Bitcoiners and crypto enthusiasts!
I'm excited to introduce Gargona, a lightweight C-based system for encrypted, time-locked messaging. Imagine sending a secret message that stays "locked" until a specified time (unlock_at), then unlocks for the recipient and expires (expire_at). The server only sees ciphertext—full privacy, no keys stored server-side.
Key Features:
End-to-End Encryption: RSA for key exchange + AES-GCM for message encryption (GCM tags for authentication).
Time-Locked Logic: Messages stay encrypted, unlock on a timer, and auto-delete after expiration.
Ring Buffer: Up to 1024 messages per recipient, oldest/expired messages removed automatically.
Listen Modes: live (unlocked messages), all (with metadata), single (specific key).
Lightweight & Decentralized: Self-hosted server, no external DBs. Planning P2P replication (gossip/Raft, no Redis/Postgres).
Why Gargona? Perfect for whistleblower tools, time capsules, corporate alerts, or dead man's switches. Secure, fast, no compromises—the server can't read your secrets.

Feedback, replication ideas, or contributions welcome in issues or here. Let’s make decentralized alerting a reality! 🚀
What do you think? Ready to test it? 😎
