Most existing Java clients pre‑date Project Loom and therefore rely on traditional thread‑per‑connection models, leading to high thread‑count overhead. Recent native clients have adopted async I/O (epoll/kqueue) to achieve high concurrency. iJavTorrent leverages to achieve a comparable level of concurrency while retaining Java’s safety guarantees. | BEP 47 | | Peer ID obfuscation

| Feature | Description | Standard | |---------|-------------|----------| | for tracker/DHT | Server‑authentication via X.509, forward secrecy via AEAD ciphers. | RFC 8446 | | MSE/PE (fallback) | RC4‑based encryption with key negotiation. | BEP 6 | | Message Authentication | HMAC‑SHA256 attached to each protocol message (except handshake). | BEP 47 | | Peer ID obfuscation | Randomized client identifier per session to hinder fingerprinting. | – | | IP filtering | Optional deny‑list (CIDR) to block known malicious peers. | – | | Rate‑limit per‑peer | Prevents DoS by throttling peers that exceed configurable thresholds. | – |
