## 🚀 How to Publish

### Prerequisites
1. Install tools:
   ```bash
   pip install build twine
   ```

2. Create PyPI account: https://pypi.org/account/register/

3. Get API token: https://pypi.org/manage/account/token/

4. Configure credentials:
   - Windows: `%USERPROFILE%\.pypirc`
   - Linux/Mac: `~/.pypirc`
   - Use `.pypirc.example` as template

### Quick Publish (3 Commands)

```bash
# Package is already built in dist/
cd D:\code\sm-bc\sm-py-bc

# Check (already done, but verify)
twine check dist/*

# Upload to PyPI
twine upload dist/*
```

### Test First (Recommended)

```bash
# Upload to Test PyPI
twine upload --repository testpypi dist/*

# Test installation
pip install --index-url https://test.pypi.org/simple/ sm-py-bc

# Verify
python -c "from sm_bc.crypto.digests import SM3Digest; print('OK')"

# If OK, upload to production
twine upload dist/*
```

## ✅ Verification Checklist

- [x] `pyproject.toml` configured with PyPI metadata
- [x] `LICENSE` file exists
- [x] `MANIFEST.in` created
- [x] All `__init__.py` files present
- [x] Import paths corrected
- [x] Package built successfully
- [x] `twine check` passed
- [x] Import tests passed
- [ ] Update GitHub URLs in `pyproject.toml` (placeholder)
- [ ] Run full test suite: `pytest tests/unit/`
- [ ] Get PyPI API token

## 📝 Next Steps

1. **Update GitHub URLs** in `pyproject.toml`:
   ```toml
   [project.urls]
   "Homepage" = "https://github.com/YOUR_USERNAME/sm-py-bc"
   "Bug Tracker" = "https://github.com/YOUR_USERNAME/sm-py-bc/issues"
   ...
   ```

2. **Run Tests** (optional but recommended):
   ```bash
   pytest tests/unit/
   ```

3. **Publish**:
   - Follow `QUICK_PUBLISH.md` for fastest route
   - Or follow `PUBLISHING.md` for detailed guide
   - Use `RELEASE_CHECKLIST.md` for step-by-step

## 🎯 Post-Publication

After `twine upload`:

1. **Verify installation**:
   ```bash
   pip install sm-py-bc
   python -c "from sm_bc.crypto.cipher import create_sm4_cipher; print('✓')"
   ```

2. **Create Git tag**:
   ```bash
   git tag -a v0.1.0 -m "Release v0.1.0"
   git push origin v0.1.0
   ```

3. **Create GitHub Release**:
   - Attach `dist/sm_py_bc-0.1.0.tar.gz`
   - Attach `dist/sm_py_bc-0.1.0-py3-none-any.whl`

4. **Announce**:
   - GitHub Discussions
   - Python cryptography communities
