### 3. Test Quality ✅

**Comprehensive Coverage:**
- Bidirectional testing (Java→Python and Python→Java)
- Multiple input sizes (0B to 1KB+)
- Unicode support (Chinese, Japanese, Korean, Arabic, emojis)
- Binary data patterns (zeros, ones, alternating)
- Edge cases (empty input, boundary conditions)
- Tampering detection (invalid signatures, modified ciphertexts)
