## Modernization Summary

### What Was Accomplished
1. **Framework Upgrade**: Both projects successfully migrated from .NET 5.0 to .NET 9.0
2. **Package Updates**: All critical NuGet packages updated to latest compatible versions
3. **Security Fixes**: SkiaSharp CVE vulnerability fixed with upgrade to 3.119.1
4. **Deprecated Dependencies**: Removed Application Insights (2.16.0) which was deprecated
5. **Local Credential Encryption**: Implemented ASP.NET Core Data Protection API for secure credential storage
6. **Backward Compatibility**: Existing plaintext credentials continue to work

### Files Modified
- Marechai.Database/Marechai.Database.csproj
- Marechai/Marechai.csproj
- Marechai/Startup.cs
- Marechai/Pages/_Host.cshtml

### Files Created
- Marechai/Helpers/CredentialEncryptor.cs
- Marechai/Helpers/ConnectionStringManager.cs
- Marechai/CREDENTIAL_ENCRYPTION_GUIDE.md
- .appmod/.migration/plan.md
- .appmod/.migration/progress.md

## Build Status
✅ **Build Successful** - No compilation errors

## Architecture Notes
- All credential encryption is LOCAL-ONLY using Data Protection API (DPAPI)
- No cloud services or Azure dependencies required
- MariaDB database remains local and unchanged
- Backward compatible with existing configurations
- Graceful fallback from encrypted to plaintext credentials

## Next Steps
1. Test the application with existing MariaDB connection
2. Deploy to production environment
3. (Optional) Encrypt connection strings in production using the provided guide
