### SMB3 Encryption Support
- **SMB2 Transform Header**: Encrypted message wrapping
- **AES-CCM/GCM Support**: Both AES-128-CCM (SMB 3.0/3.0.2) and AES-128-GCM (SMB 3.1.1) cipher suites
- **Encryption Context**: Per-session encryption state management
- **Key Derivation**: SMB3 KDF implementation with dialect-specific parameters
- **Pre-Authentication Integrity**: SMB 3.1.1 PAI for preventing downgrade attacks
