Maximum privacy with dual protection —
direct peer-to-peer connection and end-to-end encryption.
Messages never touch the server and vanish permanently once the
connection ends. Only peers holding the shared key
can read them.
Secure multi-party chat with temporary
server logs. History is auto-deleted after 2 hours of inactivity or
can be cleared manually by the Admin Group. Even if logs are found,
encrypted data is unreadable without the group key.
In short, Pure P2P offers ultimate privacy with zero server storage, while P2P Group provides flexible shared conversations with encrypted, temporary logs.
| Aspect | Pure P2P | P2P Group |
|---|---|---|
| Connection | Direct 1-to-1 WebRTC peer connection | Server-mediated group chat via long polling |
| Protocol | WebRTC DataChannel | Server-based message relay |
| Encryption | AES-GCM with PBKDF2, session key stored in sessionStorage | AES-GCM with PBKDF2, derived from group password and ID |
| Session Persistence | localStorage + sessionStorage, auto reconnect | Cookies for userID and groupID |
| File Transfer | Chunked via DataChannel with retry and ACK | Not available |
| Real-Time Capability | Yes, direct peer-to-peer | Limited, polling-based updates |
| Max Peer Count | 2 | Many (group members) |
| Connection Success Rate | 70% (depends on NAT and browser) | 100% (server relay, NAT-independent) |
| Advantages | Low latency, end-to-end encryption, serverless | Supports groups, NAT-agnostic, encrypted |
| Limitations | Fails on symmetric NAT, no group support | Higher latency, server load, no file/media support |
| Best Use Case | Private 1-on-1 encrypted chat | Encrypted group text discussions |
