A high-performance REST API built with ASP.NET Core, designed to convert structured text into XSD-validated XML.Includes AES/RSA encryption, SQLite-based XML storage, background job processing via Hangfire + Redis, Swagger UI with API key authentication, and CI/CD pipeline integration.

Objective

1. Convert structured plain text to XML
2. AES & RSA encryption/decryption of XML
3. XML schema validation via XSD
4. Background XML processing using Hangfire + Redis
5. Swagger UI endpoint
6. API Key authentication middleware
7. SQLite-based XML file storage
8. CI/CD deployment to Azure App Service (via GitHub)

Tech Stack

ASP.NET Core 9 SQLite (EF Core) Serilog (logging) Swagger / OpenAPI Hangfire + Redis (background processing) Custom middleware (API key) GitHub Actions (CI/CD)

API Endpoints

POST /api/convert → Convert text to XML (sync)
POST /api/encrypt → Encrypt XML (AES or RSA)
POST /api/decrypt → Decrypt XML (AES or RSA)
POST /api/validate → Validate XML against XSD
GET /health → Health check

Note: All routes require an API key in the X-API-KEY header

Requirements

.NET 9 SDK SQLite Redis (running on localhost:6379) Visual Studio or VS Code Azure account (for deployment)

CI/CD & Deployment

1. Connected to GitHub repository with Actions
2. Auto-deployment to Azure App Service
3. Azure URL (live Swagger UI): https://dotnet-xml-api-mohsenhallaj-a4f4cacmdxe4hud8.spaincentral-01.azurewebsites.net

Testing & Logs

Local debug: dotnet run Logging: Serilog output to console + file (Logs/app.log) Swagger UI opens automatically on localhost
