Introducing SecureFetch.AspNetCore

#webdev #programming #productivity #dotnet

We’re excited to introduce SecureFetch.AspNetCore — a lightweight but powerful NuGet package that brings encrypted payloads and obfuscated routes to your ASP.NET Core APIs, without requiring major changes to your controllers.

🚀 What Is SecureFetch.AspNetCore?

SecureFetch.AspNetCore is a middleware and attribute-based system for .NET 8+ that allows you to:

🔒 Encrypt request payloads using AES-256.
🕵️‍♂️ Obfuscate route paths and query parameters, hiding sensitive routes from static scanners.
⚙️ Use as middleware — works transparently with your existing endpoints.
🧩 Supports all HTTP verbs: GET, POST, PUT, PATCH, DELETE.

It's especially useful for teams looking to add a layer of transport-level obfuscation and end-to-end encryption for frontend-to-backend communication — without relying solely on HTTPS.

✅ How It Works

Client-Side Encryption: Use the secure-fetch-sdk in your frontend to encrypt requests.
Middleware Decryption: The SecureFetch middleware decrypts and proxies incoming requests.
Controller Integration: Add the [SecureFetch] attribute to any controller method you want to secure.

🧪 Try It Out

🔗 NuGet Package: SecureFetch.AspNetCore on NuGet
🧰 Frontend SDK: secure-fetch-sdk on NPM
📘 Docs & GitHub:

securefetch.aspnetcore Docs on GitHub

secure-fetch-sdk Demo on GitHub

💡 Use Cases

Internal tools requiring stealth endpoints
Extra protection for mobile or browser-based apps
High-risk APIs that transmit sensitive data

If you're building modern .NET apps and want an extra layer of security without extra complexity, SecureFetch.AspNetCore is worth a look. ✨

Looking forward!

🐯 🚀 Timescale is now TigerData: Building the Modern PostgreSQL for the Analytical and Agentic Era

We’ve quietly evolved from a time-series database into the modern PostgreSQL for today’s and tomorrow’s computing, built for performance, scale, and the agentic future.

So we’re changing our name: from Timescale to TigerData. Not to change who we are, but to reflect who we’ve become. TigerData is bold, fast, and built to power the next era of software.
