**What Changed:**

- **Removed:** All libsodium dependencies and PAKE-based authentication
- **Replaced With:** ECDH + DTLS + SAS triple-layer security system
- **Impact:** Eliminates complex PAKE implementation in favor of standardized protocols

**Security Benefits:**
- ✅ **Simplified Architecture** - Reduced attack surface
- ✅ **Standards Compliance** - RFC-compliant protocols
- ✅ **Better Maintenance** - Native Web Crypto API usage
- ✅ **Enhanced Security** - Triple-layer defense system

**New Features:**
- **Elliptic Curve Diffie-Hellman** using P-384 (secp384r1)
- **Cryptographically secure** key pair generation
- **Perfect Forward Secrecy** with session-specific keys
- **MITM resistance** requiring knowledge of both private keys
