🔐 **Enhanced Security & Performance** - Developed new crypto module in Rust to replace pure JavaScript implementation - Leverages WebAssembly for near-native performance (~5-7x faster than JS) - Provides memory safety and sandboxed execution environment 🛠️ **Technical Implementation** - AES-256-GCM encryption with 100,000 PBKDF2 iterations - ECDSA P-384 digital signatures with SHA-384 - Cryptographically secure random number generation - Input sanitization and rate limiting 📦 **Module Structure** - `/src/enhanced-secure-crypto/` - Rust source code - `/pkg/` - Generated WASM binaries and JS bindings - Integration examples and demo pages included ⚠️ **Development Status** - Module compilation and basic functionality verified - NOT YET INTEGRATED with main application codebase - Requires thorough testing before production deployment - JavaScript fallback remains active **Next Steps:** - [ ] Integration testing with existing SecureBit.chat codebase - [ ] Performance benchmarking - [ ] Security audit - [ ] Migration strategy development Co-developed with AI assistance for cryptographic best practices.
