### Protocol Support
The library supports a full range of SMB protocols with automatic negotiation:

**Supported Protocols:**
- **SMB1/CIFS**: Legacy support via `jcifs.smb1/` package
- **SMB 2.0.2**: Windows Vista+ (0x0202)
- **SMB 2.1**: Windows 7/Server 2008R2 (0x0210)
- **SMB 3.0**: Windows 8/Server 2012 (0x0300) - AES-128-CCM encryption
- **SMB 3.0.2**: Windows 8.1/Server 2012R2 (0x0302) - Enhanced encryption
